firewire: sbp2: fold two functions into one

Browse source 
sbp2_release_target() is folded into its primary user, sbp2_remove().
The only other caller, a failure path in sbp2_probe(), now uses
sbp2_remove().  This adds unnecessary cancel_delayed_work_sync() calls
to that failure path but results in less code and text.
