[PATCH] ACPICA: events/evxfregn: don't release the ContextMutex that was never acquired

[Daniil Tatianin]

This bug was first introduced in c27f3d011b08, where the author of the
patch probably meant to do DeleteMutex instead of ReleaseMutex. The
mutex leak was noticed later on and fixed in e4dfe108371, but the bogus
MutexRelease line was never removed, so do it now.

Fixes: c27f3d011b08 ("Fix race in GenericSerialBus (I2C) and GPIO OpRegion parameter handling")
