qcacld-3.0: Avoid calling decrement session twice in SAP removal

While disabling SAP session, policy_mgr_decr_session_set_pcl()
is getting called twice, one from mc_thread (hdd_hostapd_sap_
event_cb()) and other from hostapd (__wlan_hdd_cfg80211_stop
_ap()). This can corrupt the pm_conn_connection_info table.

This change removes policy_mgr_decr_session_set_pcl() getting
called from hdd_hostapd_sap_event_cb().
