Don't allocate an input buffer for a TTY when the receiver is turned off.

When the termios CREAD flag is not set, it makes little sense to
allocate an input buffer. Just set the size to 0 in this case to reduce
memory footprint.

Disallow CREAD to be disabled for pseudo-devices to prevent
foot-shooting.
