From: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com>
kbdif protocol describes multi-touch device parameters as a part of frontend's XenBus configuration nodes while they belong to backend's configuration. Fix this by reading the parameters as defined by the protocol.
Fixes: 49aac8204da5 ("Input: xen-kbdfront - add multi-touch support")
