qcacld-3.0: Send pmk cmd even PMKSA entry is found

Currently, supplicant uses two different ways to delete PMKSA entry,
one uses SSID and cache ID as keywords, another one uses BSSID as
keywords. It causes out of sync between fw and host if driver adds
PMKSA entry with BSSID and supplicant deletes PMKSA entry with SSID
and cache ID.

To resolve this issue, send pmk cmd to fw even the PMKSA entry is
found.
