LU-13464 target: abort recovery if timer fail

During target recovery, the recovery timer should be kept to be
armed to ensure the recovery doesn't take too long time, there
should be some problem if the deadline of the recovery timer is
passed and the recovery is not completed yet, the recovery should
be aborted in this case.
