[ Upstream commit b819447dfc4bd120c9d6cd8521252d544fce8fe7 ]
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.
