x86/xen: Fix boot loader version reported for PVH guests
The boot loader version reported via sysfs is wrong in case of the
kernel being booted via the Xen PVH boot entry. it should be 2.12
(0x020c), but it is reported to be 2.18 (0x0212).
As the current way to set the version is error prone use the more
readable variant (2 << 8) | 12.
