If the lock request was rejected by a set member we should
restore any previously written logs in reverse order.
However there was a off-by-one error in
csip_set_coordinator_write_lock_cb which caused us to attempt to
release member[1] instead of member[0] if member[1] was the
one that rejected the lock request.
Additionally, the lock_set_complete would be called
prematurely before we get the response from the restore
request.
