Currently, devpts doesn't generate an fsnotify event upon pts creation
because the regular vfs paths aren't involved. Deallocation, on the
other hand, correctly generates a nameremove event thanks to the
d_delete() invocation in devpts_pty_kill().
This patch adds the missing fsnotify_create() trigger in devpts_pty_new().
