kernel/timeout: Refactor z_clock_announce() loop
This loop was structured badly, as a while(true) with multiple "exit
if" cases in the body. It was bad enough that I genuinely fooled
myself into rewriting it, having convinced myself there was a bug in
it when there wasn't.
So keep the rewritten loop which expresses the iteration in a more
invariant way (i.e. "while we have an element to expire" and not "test
if we have to exit the loop"). Shorter and easier. Also makes the
locking clearer as we can simply release the lock around the callback
in a natural/obvious way.
