sched: Re-add lost cpu_allowed check to sched_fair.c::select_task_rq_fair()

Browse source

While doing some testing, I pinned mplayer, only to find it
following X around like a puppy. Looking at commit c88d591, I found
a cpu_allowed check that went AWOL.  I plugged it back in where it
looks like it needs to go, and now when I say "sit, stay!", mplayer
obeys again.

'c88d591 sched: Merge select_task_rq_fair() and
sched_balance_self()' accidentally dropped the check, causing
wake_affine() to pull pinned tasks - put it back.

[ v2: use a cheaper version from Peter ]
