scst_local_add_target(): Also set *out_tgt upon failure

Browse Source 
Although the callers of scst_local_add_target() do not use the
value of *out_tgt if scst_local_add_target() reports that it failed,
set *out_tgt in that case to avoid that sparse reports the following
(false positive) warning:

scst_local/scst_local.c:1807: warning: 'tgt' may be used uninitialized in this function
