target: Fix free-after-use regression in PR unregister
This patch addresses a >= v3.11 free-after-use regression
in core_scsi3_emulate_pro_register() that was introduced
in the following commit:
commit bc118fe4c4a8cfa453491ba77c0a146a6d0e73e0
Author: Andy Grover <agrover@redhat.com>
Date: Thu May 16 10:41:04 2013 -0700
target: Further refactoring of core_scsi3_emulate_pro_register()
To avoid the free-after-use, save an type value before hand, and
only call core_scsi3_put_pr_reg() with a valid *pr_reg.
