Commit 67fd4fcb (e1000e: convert to stats64) added the ability to update
statistics more accurately and on-demand through the net_device_ops
.ndo_get_stats64 hook, but introduced a locking bug on 82577/8/9 when
linked at half-duplex (seen on kernels with CONFIG_DEBUG_ATOMIC_SLEEP=y and
CONFIG_PROVE_LOCKING=y).  The commit introduced code paths that caused a
mutex to be locked in atomic contexts, e.g. an rcu_read_lock is held when
irqbalance reads the stats from /sys/class/net/ethX/statistics causing the
mutex to be locked to read the Phy half-duplex statistics registers.

The mutex was originally introduced to prevent concurrent accesses of
resources (the NVM and Phy) shared by the driver, firmware and hardware
a few years back when there was an issue with the NVM getting corrupted.
It was later split into two mutexes - one for the NVM and one for the Phy
when it was determined the NVM, unlike the Phy, should not be protected by
the software/firmware/hardware semaphore (arbitration of which is done in
part with the SWFLAG bit in the EXTCNF_CTRL register).  This latter
semaphore should be sufficient to prevent resource contention of the Phy in
the driver (i.e. the mutex for Phy accesses is not needed), but to be sure
the mutex is replaced with an atomic bit flag which will warn if any
contention is possible.

Also add additional debug output to help determine when the sw/fw/hw
semaphore is owned by the firmware or hardware.

The recent changes to only power the device when the interface up
introduced a bug: changing interface type, legal when the interface

Fix this functionality by validating and recording the interface

mwifiex: use separate wait condition for each command node

Currently global wait condition (adapter->cmd_wait_q.condition)
is used while sending synchronous commands to FW. When two threads
enter in mwifiex_send_cmd_sync() routine at the same time, both the
threads wait for their command responses. Since wait condition is
same for both, they wake up simultaneously after getting response
of 1st command. After this when a thread is waiting for command
response of 3rd command, it wakes up after getting response of 2nd
command and so on. Therefore we don't wait for the response of last
command(0xaa) during unload. Hence while next time loading the driver
command time out is seen for INIT command.

This problem is resolved by having separate wait condition flag for
each command(except scan command). Since scan command is treated
differently (by maintaining scan pending q etc.), newly defined flag
(scan_wait_q_woken) is used as a scan wait condition.
