After reviewing the logic at the function, instead of just adding a patch to
revert the wrong one, the better is to apply a different logic: add a goto
that will always unlock and return the error.
This simplifies the code a little bit, and, instead of just return -EINVAL,
it will return the error condition reported by the called functions.
This patch is folded with another patch from Dan that added one missing
goto.
