Revert "USB: quatech2: only write to the tty if the port is open."

This reverts commit 27b351c. Calling tty_flip_buffer_push on an unopened tty is legal, so the driver doesn't need track if port has been opened. Reverting this allows the entire is_open logic to be removed. Signed-off-by: Bill Pemberton <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
