qcacld-3.0: Allow SAP to move to unsafe channel if ini allows

User may set the ini param g_sta_sap_scc_on_lte_coex_chan=1 if SAP
is allowed to come up on unsafe channels. Currently, this doesn't
cover the below case,
1. SAP is enabled on a 5 GHz channel in a non-DBS platform
2. Concurrent STA enabled and connected it to an AP that's in
   unsafe channel.
3. SAP doesn't move to the STA channel though the ini to enable
   force SCC(gWlanMccToSccSwitchMode) is set and it's a non-DBS
   platform as the target channel(STA channel) is unsafe channel.

Allow SAP to move to unsafe STA channel if the ini
g_sta_sap_scc_on_lte_coex_chan is set to true.
