target: Fix incorrect se_cmd assignment in core_tmr_drain_tmr_list

commit 80ccbc8e00f7001d79dd503c2781487906b98611 upstream.

This patch fixes a bug in core_tmr_drain_tmr_list() where drain_tmr_list
was using the wrong se_tmr_req for cmd assignment due to a typo during the
LUN_RESET re-org.  This was resulting in general protection faults while
using the leftover bogus *tmr_p pointer from list_for_each_entry_safe().
