qcacld-3.0: Avoid repeatedly call dump station API

Browse Source 
For AP/P2P GO mode, API wlan_hdd_cfg80211_dump_station() is designed to
return multiple records in a loop until the last record is returned. So,
return -ENOENT if there are no more entries to dump.

For STA/P2P client mode, it is designed to return self record.

Add checking index, it should return -ENOENT for station/p2p client mode
if index not zero. Otherwise, kernel will repeatedly call dump API.
