From: Florin Malita <fmalita@gmail.com>

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().
