    wpa_supplicant: Update to Version 0.8.27 from BRCM

    - Fix crash during TRUE pbc overlap
    - Fix p2p_stop_find event
    - Avoid race condition in GO-NEG process if both peers enter
      p2p_connect at the same time
    - Retry assoc immediately on ASSOC-REJECT. Previously assoc was
      retried on authentication timeout (which occurs after 10secs).
      Now on assoc reject, we cancel the auth timer and then initiate
      a assoc scan.

    BUG: 6543705, 6427094
