qcacld-3.0: Use correct API to check SAP operating on DFS

Currently use wlan_reg_chan_has_dfs_attribute_for_freq() to check SAP
start on DFS channel or not, it only check home channel not check other
channel in bandwidth. It may cause SAP on channel DFS channel go to
suspend, for example on channel 36 with bandwidth 160 MHz.

Use sap_chan_bond_dfs_sub_chan() API to check if home channel or other
channel in bandwidth is DFS channel, so that wakelock can correct hold
if SAP start on such DFS channel.
