[PATCH] module owner for ppp_synctty.c

This patch fixes ppp_synctty.c (used for doing PPP over some synchronous
serial HDLC links) so that it sets the owner field of the tty line
discipline it exports, rather than using MOD_INC/DEC_USE_COUNT.  This
is more or less from Stephen Hemminger.

Please apply.

Thanks,
Paul.
