[SCSI] qla2xxx: Fix race that could hang kthread_stop()
There is a small race window in qla2x00_do_dpc() between
checking for kthread_should_stop() and going to sleep after
setting TASK_INTERRUPTIBLE. If qla2x00_free_device() is called
in this window, kthread_stop will wait forever because there
will be no one to wake up the process.
Fix by making sure we only set TASK_INTERRUPTIBLE before checking
kthread_stop().
