staging: dgap: use schedule_timeout_interruptible() instead of dgap_ms_sleep()
Using schedule_timeout_interruptible() is exactly same as
setting a status of current process and calling schedule_timeout().
Removes dgap_ms_sleep(), because this function is used
only when closing tty channel on dgap_tty_close().
And also removes ch_close_delay that is always set to 250
on dgap_tty_init().
