[SCSI] libfc: fix: empty zone causes endless discovery retries.
On some switches, an empty zone causes GPN_FT to be rejected
with reason 9 (unable) explanation 7 (FC-4 types not registered),
which causes discovery to be retried endlessly. Treat this as
just an empty response and consider discovery complete.
