[PATCH] devpts: add fsnotify create event

[Florin Malita]

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().
