qcacld-3.0: Avoid possible heartbeat failure due to Hw-DTIM

Browse source 
In case of STA + SAP, when STA connect to a new AP, the SAP
initiate channel switch to the new channel of the STA. During
this transition period DUT will be in MCC scenario and thus
firmware changes the TBTT of SAP to get 50% channel time.

Due to this peer STA connected to DUT-SAP may miss all 5
beacons containing CSA info and when it comes out of hw-dtim
mode after 5 beacon misses the DUT SAP has already moved to
new channel and thus as SAP is not on the old channel the peer
STA will receive Heart beat failure.

To avoid this Heart beat failure on peer STA, increases the
default value of channel switch count (g_sap_chanswitch_beacon_cnt)
to 10 to increase the probability of receiving beacons with
CSA info.
