target: Change target_submit_cmd() to return void
Retval not very useful, and may even be harmful. Once submitted, fabrics should expect a sense error if anything goes wrong. All fabrics checking of this retval are useless or broken: fc checks it just to emit more debug output. ib_srpt trickles retval up, then it is ignored. qla2xxx trickles it up, which then causes a bug because the abort goto in qla_target.c thinks cmd hasn't been sent to target. Just returning nothing is best. Signed-off-by: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
