wifi: brcmfmac: cyw: pass PMKID to firmware if present
Zero out auth_status on initialization. Otherwise, garbage will
leak from the stack to the firmware (when ssid is less than 32 bytes
and/or when params->pmkid is set). Then, pass the params->pmkid to the
firmware (without it, the firmware caches a garbage PMKID on successful
authentication and denies a subsequent association request that includes
the PMKID).
