sched: Fix cfs_bandwidth misuse of hrtimer_expires_remaining
commit db06e78cc13d70f10877e0557becc88ab3ad2be8 upstream.
hrtimer_expires_remaining does not take internal hrtimer locks and thus
must be guarded against concurrent __hrtimer_start_range_ns (but
returning HRTIMER_RESTART is safe). Use cfs_b->lock to make it safe.
