As mentioned by Ingo, the SCHED_FEAT_OWNER_SPIN scheduler feature
bit was really just an early hack to make with/without mutex-spinning
testable. So it is no longer necessary.
This patch removes the SCHED_FEAT_OWNER_SPIN feature bit and move the
mutex spinning code from kernel/sched/core.c back to kernel/mutex.c
which is where they should belong.

Please move this patch first in the series - so that later, functional patches are
easier to revert, should the need arise. When possible we sort patches by risk:
low risk ones first, riskier come later.
I have sent out a new series (v4) with the requested changes. Please let
me know what else do you think I need to do.
Regards,
Longman
