waitid(): Avoid unbalanced user_access_end() on access_ok() error
As pointed out by Linus and David, the earlier waitid() fix resulted in
a (currently harmless) unbalanced user_access_end() call. This fixes it
to just directly return EFAULT on access_ok() failure.
Fixes: 96ca579a1ecc ("waitid(): Add missing access_ok() checks")
