qcacld-3.0: Get SAP adapter of DFS with correct condition

Currently hdd_get_sap_adapter_of_dfs() only check home channel is
DFS or not, but didn't consider other channel in bandwdith.
It caused can't get SAP adapter which home channel is non-DFS but
channel in bandwidth has DFS channel.

Update this function to check DFS with channel frequency and bandwidth.
