This debugfs file is really old, and cannot work properly since

which is difficult now due to multiple images (LMAC/UMAC etc.)
just remove it - we no longer need it since we properly do a FW
coredump even in D3 cases.

will go through iwl_fw_dbg_collect_sync.

In order to make more sense out of the captured radiotap data e.g.

This is made race-free by updating the included value from inside
the RX path (using a notification wait) for the command response
from the firmware, which thus means it's serialized with frame RX.

For now, RX aggregation must be disabled to use this feature
on data frames as we haven't found a good way to attach the

iwlwifi: mvm: clean up LDBG config command usage

Clean up the LDBG config command to not be called "continuous
recording", and while at it actually remove the continuous
recording implementation completely since it was only used for
store & forward architectures.

This also fixes a bug at least in iwl_fw_dbg_buffer_allocation()
because what's now "__le32 type" (matching the firmware) used to
be "__le16 enable_recording", so the buffer allocation config
sub-struct would erroneously have started at the wrong offset.
In the other cases this didn't actually lead to a bug as other
bytes in pad[] were all zeroes, so accessing the 16-bit value as
a 32-bit value wouldn't make a difference (in little endian.)

iwlwifi: avoid collecting firmware dump if not loaded

Trying to collect firmware debug data while firmware
is not loaded causes various errors (e.g. failing NIC access).
This causes even a bigger issue if at that time the
HW radio is off.
In that case, when later turning the radio on, the Driver
fails to read the HW (registers contain garbage values).
(It may be that the CSR_GP_CNTRL_REG_FLAG_RFKILL_WAKE_L1A_EN
bit is cleared on faulty NIC access - since the same behavior
was seen in HW RFKILL toggling before setting that bit.)
