3.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steve Hodgson <st...@purestorage.com>
commit ab74b3d62f05192bf8fb8f169e7999d1183b2e08 upstream.
This patch changes core_tmr_abort_task() to use spin_lock -> spin_unlock
around se_cmd->t_state_lock while spin_lock_irqsave is held via
se_sess->sess_cmd_lock.
