qcacld-3.0: Reset CAC state if another AP is not on 5GHz

In case of DBS, two AP can operate on different band together.
Current logic of resetting CAC state in sap_clear_global_dfs_param
function assumes that if two APs are up state then it must be SCC
scenario and resulting in dropping of tx packets if stop follwed by
start operation is performed on AP on DFS channel.

This change reset CAC state as part of stop AP if another AP is
operating on 2.4GHz in case of DBS operation.
