qcacld-3.0: Replace hdd_context_t in __iw_get_peer_rssi()

Previously change "qcacld-3.0: Replace hdd_context_t in
wlan_hdd_hostapd.[ch]" replaced all instances of hdd_context_t in
wlan_hdd_hostapd.c. However a subsequent change introduced
__iw_get_peer_rssi() which has a new instance, so replace it.
