ntdll: Fix buffer allocation check in get_dir_data_space.

size already includes the terminating \0 character.

BTW: I assume its intentional that you realloc only the first buffer to release
     some space, right? In the worst case we are wasting up to about
     PATH_MAX * sizeof(WCHAR) space in the other buffers.
