Sebastian Andrzej Siewior 73c6c02b4f futex: Correct the kernedoc return value for futex_wait_setup(). ...

The kerneldoc for futex_wait_setup() states it can return "0" or "<1".
This isn't true because the error case is "<0" not less than 1.

Document that <0 is returned on error. Drop the possible return values
and state possible reasons.
