target: Fix missing length check in spc_emulate_evpd_83()
Commit fbfe858fea2a ("target_core_spc: Include target device descriptor in VPD page 83") added a new length variable, but (due to a cut and paste mistake?) just checks scsi_name_len against 256 twice. Fix this to check scsi_target_len for overflow too. Signed-off-by: Roland Dreier <roland@purestorage.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
