1. ptmx_open -> pty_register2 -> master register i_crefs 1
-> salve register i_crefs 1
2. ptmx_open -> master unregister i_crefs 0
3. master open i_crefs 1
salve open i_crefs 2
4. in pty_close() master close with i_crefs 1
salve close with i_crefs 2
So, if correct the i_crefs judgement in pty_close()
