3.11.10.3 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Shivaram Upadhyayula <shivaram.u@xxxxxxxxxxxx>
commit 63832aabec12a28a41a221773ab3819d30ba0a67 upstream.
This patch fixes two cases in qla_target.c code where the
schedule_delayed_work() value was being incorrectly calculated
from sess->expires - jiffies.
