qcacld-3.0: Fix some whunt build errors

1) In function hdd_process_genie(), there is a chance for
   the 2 incoming parameters, encrypt_type and
   mc_encrypt_type, not initialized due to an error
   condition.

2) Remove some of the local variables that are not used
   anymore in the following functions:

   __wlan_hdd_cfg80211_del_station
   hdd_features_init
   hdd_cleanup_present_mode
   hdd_update_regdb_offload_config
   __wlan_hdd_cfg80211_scan
   hdd_softap_stop_bss
