wlan: Prevent deadlock while acquiring hdd adapter lock
It is possible one of thread (TX/RX/MC) acquired hdd adapter
lock, But at same time kernel raised the software interrupts
/ Soft irq's on same CPU. For e.g Driver IPV 4/6 change handler
get invoked in soft irq context. While driver is processing
these irq's, it will again try to acquire the adapter lock
which is hold by Thread context. Hence lead to deadlock.
As a part of this fix, Driver will Disable software interrupts
before acquiring hdd adapter lock.
