brcmfmac: set state of hanger slot to FREE when flushing PSQ
When USB or SDIO device got abnormal bus disconnection, host driver tried to clean up the skbs in PSQ and TXQ (The skb's pointer in hanger slot linked to PSQ and TSQ), so we should set the state of skb hanger slot to BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb. In brcmf_fws_bus_txq_cleanup it already sets BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb, therefore we add the same thing in brcmf_fws_psq_flush to avoid following warning message.

brcmfmac: map 802.1d priority to precedence level based on AP WMM params
In WLAN, priority among various access categories of traffic is always set by the AP using WMM parameters and this may not always follow the standard 802.1d priority.
In this change, priority is adjusted based on the AP WMM params received as part of the Assoc Response and the same is later used to map the priority of all incoming traffic.
In a specific scenario where EDCA parameters are configured to be same for all ACs, use the default FW priority definition to avoid queuing packets of all ACs to the same priority queue.
This change fixes the following 802.11 certification tests: * 11n - 5.2.31 ACM Bit Conformance test * 11n - 5.2.32 AC Parameter Modification test * 11ac - 5.2.33 TXOP Limit test

brcmfmac: Fix double freeing in the fmac usb data path
When the brcmf_fws_process_skb() fails to get hanger slot for queuing the skb, it tries to free the skb. But the caller brcmf_netdev_start_xmit() of that funciton frees the packet on error return value. This causes the double freeing and which caused the kernel crash.

brcmfmac: fix NULL pointer derefence during USB disconnect
In case USB disconnect happens at the moment transmitting workqueue is in progress the underlying interface may be gone causing a NULL pointer dereference. Add synchronization of the workqueue destruction with the detach implementation in core so that the transmitting workqueue is stopped during detach before the interfaces are removed.
Fix following Oops:

brcmfmac: fix WARNING during USB disconnect in case of unempty psq
brcmu_pkt_buf_free_skb emits WARNING when attempting to free a sk_buff which is part of any queue. After USB disconnect this may have happened when brcmf_fws_hanger_cleanup() is called as per-interface psq was never cleaned when removing the interface. Change brcmf_fws_macdesc_cleanup() in a way that it removes the corresponding packets from hanger table (to avoid double-free when brcmf_fws_hanger_cleanup() is called) and add a call to clean-up the interface specific packet queue.
Below is a WARNING during USB disconnect with Raspberry Pi WiFi dongle running in AP mode. This was reproducible when the interface was transmitting during the disconnect and is fixed with this commit.
