wifi: mt76: mt7921s: fix potential hung tasks during chip recovery

wifi: mt76: mt7921s: fix potential hung tasks during chip recovery
[ Upstream commit ecf0b2b8a37c8464186620bef37812a117ff6366 ]
During chip recovery (e.g. chip reset), there is a possible situation that
kernel worker reset_work is holding the lock and waiting for kernel thread
stat_worker to be parked, while stat_worker is waiting for the release of
the same lock.
It causes a deadlock resulting in the dumping of hung tasks messages and
possible rebooting of the device.
This patch prevents the execution of stat_worker during the chip recovery.

wifi: mt76: mt7921s: fix workqueue problem causes STA association fail

wifi: mt76: mt7921s: fix workqueue problem causes STA association fail
[ Upstream commit 92184eae1d5ad804884e2c6e289d885b9e3194d1 ]
The ieee80211_queue_work function queues work into the mac80211
local->workqueue, which is widely used for mac80211 internal
work processes. In the mt76 driver, both the mt76-sido-status and
mt76-sdio-net threads enqueue workers to the workqueue with this
function. However, in some cases, when two workers are enqueued
to the workqueue almost simultaneously, the second worker may not
be scheduled immediately and may get stuck for a while.
This can cause timing issues. To avoid these timing
conflicts caused by worker scheduling, replace the worker
with an independent thread.
