Subject: target: fix buffer offset in core_scsi3_pri_read_full_status
From: tangwenji <tang.wenji@zte.com.cn>
commit c58a252beb04cf0e02d6a746b2ed7ea89b6deb71 upstream.
When at least two initiators register pr on the same LUN,
the target returns the exception data due to buffer offset
error, therefore the initiator executes command 'sg_persist -s'
may cause the initiator to appear segfault error.
This fixes a regression originally introduced by:
commit a85d667e58bddf73be84d1981b41eaac985ed216
