wl12xx: fix Tx security sequence number handling
Do not reset the security sequence number when issuing a join command or
interface is removed. Instead, reset the counter only during the unjoin
command.
Added the notion of counter wrap-around to the LSB number in
wl1271_tx_complete_packet.
Added post recovery padding to adjust for potential security number
progress during the recovery process by the firmware and avoid
potential interop issues in encrypted networks.
