ath11k: fix fw crash due to peer get authorized before key install

Browse source

Firmware expects host to authorize the peer after the successful key
install. But host authorize the peer before the key install, this trigger
the firmware assert which leads to Q6 crash. To avoid this Q6 crash, host
should authorize the peer after the key install. So introduce is_authorized
in peer object to identify that peer is authorize or not. When
IEEE80211_STA_CONTROL_PORT flag is unset, peer move to authorize state
before the vdev up. When the same flag is set then peer move to authorize
state after vdev up. So added authorise check in ath11k_bss_assoc() to
handle the earlier state transition case. Also added the WMI authorize
procedure in ath11k_mac_op_sta_state() to handle the non-earlier state
transition case.
