firewire: fw-sbp2: fix races
1: There is a small race between queue_delayed_work() and its
corresponding kref_get(). Do the kref_get first, and _put it again
if the queue_delayed_work() failed, so there is no chance of the
kref going to zero while the work is scheduled.
2: An SBP2_LOGOUT_REQUEST could be sent out with a login_id full of
garbage. Initialize it to an invalid value so we can tell if we
ever got a valid login_id.
3: The node ID and generation may have changed but the new values may
not yet have been recorded in lu and tgt when the final logout is
attempted. Use the latest values from the device in
sbp2_release_target().
