qcacld-3.0: Fix stop_bss_event timeout issue

Browse Source 
Sometimes 'qdf_event_set(&hostapd_state->qdf_stop_bss_event)'
is invoked from 'wlansap_stop_bss' in other thread before
invoking 'qdf_event_reset(&hostapd_state->qdf_stop_bss_event)'.
Then 'stop_bss_event' timeout happens even if 'qdf_stop_bss_event'
has been set.

To fix this issue, make sure 'qdf_event_reset(&hostapd_state->
qdf_stop_bss_event)' happens before 'wlansap_stop_bss'.
