kernel/queue: Clean up scheduler API usage

This was the only spot where the scheduler-internal
_peek_first_pending_thread() API was used.  Given that this kind of
thing is inherently racy (it may not be pending as long as you expect
if a timeout expires, etc...), it would be nice to retire it.

And as it happens all the queue code was using it for was to detect
the case of a non-empty wait_q over which it was looping, which is
trivial to do without API support.
