target: Alter core_pr_dump_initiator_port for ease of use
We use this function exclusively in debug prints. Instead of returning 0 or 1 if isid is present, just set buf to "" if it isn't there. This saves callers from having to check the return value. Signed-off-by: Andy Grover <agrover@redhat.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
