inotify: _inotify.c: bugfix: remove_watch has to return PyNone on success

We are not currently using that API function in inotify, hence the reason
for the "silent" bug. But returning NULL here causes the interpreter to crash.
Let's keep code clean for reusers :)

The whole "bail" logic was unneeded here.
