x86/xen/gdt: Use X86_FEATURE_XENPV instead of globals for the GDT fixup
Xen imposes special requirements on the GDT. Rather than using a
global variable for the pgprot, just use an explicit special case
for Xen -- this makes it clearer what's going on. It also debloats
64-bit kernels very slightly.
