wil6210: fix protection against connections during reset

Browse Source 
Existing code that ignores connection events during
reset flow will never take effect since it locks the
same mutex taken by the reset flow.

In addition, in case of unsolicited disconnect events ignore
those as well since device is about to get reset.
