tcm_fc: Convert to wake_up_process and schedule_timeout_interruptible
This patch converts ft_queue_cmd() to use wake_up_process() and ft_thread() to use schedule_timeout_interruptible(MAX_SCHEDULE_TIMEOUT) instead of wait_event_interruptible(). This fixes a potential race with the wait_event_interruptible() conditional with qobj->queue_cnt in ft_thread(). This patch also drops the unnecessary set_user_nice(current, -20) in ft_thread(), and drops extra () around two if (!(acl)) conditionals in tfc_conf.c.
