futex: Fix might_sleep() warning in futex_pivot_pending()
A younger me put a WARN in might_sleep() to warn about nested sleep loops. This
younger me also build a wait-loop variant that can deal with it. This wait-loop
variant doesn't have all the fancy wrappers, since it isn't used much. It also
lacks wait-bit support.
Add the wait-bit support and use it to fix the nested wait issue.
