rtos: Rewrite rtos_try_next() for readability

The new code is almost functionally equivalent to the old.

The function now returns 0 instead of -1 if target->rtos has not yet
been allocated. All call sites only test for success, and in practise
that is also the only thing that matters; if the function successfully
iterated to the next RTOS or not.

Other than that the only difference is that the code is now readable.

Many thanks to Matthias Blaicher for the fix to the iteration error!
