scsi: target: fix PR IN / READ FULL STATUS for FC
[ Upstream commit 8fed04eb79a74cbf471dfaa755900a51b37273ab ]
Creation of the response to READ FULL STATUS fails for FC based
reservations. Reason is the too high loop limit (< 24) in
fc_get_pr_transport_id(). The string representation of FC WWPN is 23 chars
long only ("11:22:33:44:55:66:77:88"). So when i is 23, the loop body is
executed a last time for the ending '\0' of the string and thus hex2bin()
reports an error.
