sched/fair: don't skip based on target capacity

commit 434dab22 ("sched/fair: do not
reset target_capacity") removed the snippet that skipped processing cpus
with higher capacity than the target.

This was because the skip was done later in the loop which did not
process further cpus unless we are in boost and have higher capacity
to visit next.

However a recent merge from upstream reintroduced this snippet.
commit b2c84630 ("Merge
android-4.14-p.61 (b7e55e84) into msm-4.14").

Remove that snippet again.
