wil6210: Protect against false interrupt during reset sequence

Browse source 
During reset sequence it is seen that device is generating an
interrupt eventhough interrupts are masked at device level.

Add workaround to disable the interrupts from host side during
reset and clear any pending interrupts before re-enabling
the interrupt.
