qcacld-3.0: Set acs complete in wlan_hdd_cfg80211_acs_ch_select_evt

Browse source 
Currently the acs in progress is not set to 0 when
acs policy is 1 and the control returns the best channel
in do acs itself, hence it can lead to many unexpected
behaviour if set to 1 and acs is complete.
For example one case sceanrio is that the driver
returned from do acs without clearing the acs
in progress flag, and then stop adapter comes to
the driver for the same interface, the driver
would check that if acs in progress is tru then
it would wait for 3 seconds for it to complete.
Now since there is no complete to be there as
ACS had already been completed, there would be
an unnecessary delay for 3 seconds to shutdown
SAP which would cause latency.

Fix is to set the acs in progress as 0 when the overide
happens.
