[RFC v2 PATCH 1/8] sched: Rename sched_rt_period_mask() and use itin CFS also

[Bharata B Rao]

sched: Rename sched_rt_period_mask() and use it in CFS also.

From: Bharata B Rao <bharata@xxxxxxxxxxxxxxxxxx>

sched_rt_period_mask() is needed in CFS also. Rename it to a generic name
and move it to kernel/sched.c. No functionality change in this patch.
