qcacld-3.0: Fix set hw mode completion event not reset

During vdev destroy, normally driver will wait for set hw mode
completion before cancel the nonscan serialization Command.
But the “wait” doesn't happen at some time. The reason could be
the qdf event (set hw complete event) is signaled state at the
time of waiting. There are code path the event is set without
reset during hw mode change.
Fix by reset the event in csr_process_set_hw_mode alone with
setting the hw_mode_change_in_progress flag.
