qcacld-3.0: Remove enable_snr_monitoring from hdd_config struct

Currently, enable_snr_monitoring doesn't be initialized properly, in
some acs scenario, hostapd will dump survey(NL80211_CMD_GET_SURVEY),
driver return error due to uninitialized enable_snr_monitoring, this
will result in acs won't be started and sap fail to start.

Fix is to remove enable_snr_monitoring from hdd_config struct,
calling ucfg_scan_is_snr_monitor_enabled() everywhere that
enable_snr_monitoring is being used.
