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.
