iscsi-target: Fix snprintf usage with MAX_PORTAL_LEN
This patch makes lio_target_call_addnptotpg() use sprintf() with MAX_PORTAL_LEN + 1 to address the following smatch warning: drivers/target/iscsi/iscsi_target_configfs.c +184 lio_target_call_addnptotpg(21) error: snprintf() chops off the last chars of 'name': 257 vs 256 Reported-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
