Disconnection is logged even if keepalive indication is
sent to host after firmware sending final beacon miss
event.
Add two new roam failure reason code to indicate roam
failure and send final beacon miss.
ROAM_FAIL_REASON_NO_AP_FOUND_AND_FINAL_BMISS_SENT: Indicate
roam failure when no ap is found and final beacon miss
is sent.
ROAM_FAIL_REASON_NO_CAND_AP_FOUND_AND_FINAL_BMISS_SENT:
Indicate roam failure when no candidate ap is found and
final beacon miss is sent.
