[PATCH v9 1/4] chardev/char-pty: send CHR_EVENT_CLOSED on disconnect

[Roman Penyaev <r.peniaev@gmail.com>]

Change makes code symmetric to the code, which handles
the "connected" state, i.e. send CHR_EVENT_CLOSED when
state changes from "connected" to "disconnected".

This behavior is similar to char-socket, for example.
