Shawn Bohrer 6bfa687c19 sched/rt: Remove redundant nr_cpus_allowed test 
In 76854c7e8f ("sched: Use
rt.nr_cpus_allowed to recover select_task_rq() cycles") an
optimization was added to select_task_rq_rt() that immediately
returns when p->nr_cpus_allowed == 1 at the beginning of the
function.

This makes the latter p->nr_cpus_allowed > 1 check redundant,
which can now be removed.
