x86/gdt: Fix setup_fixmap_gdt() to use the correct PA
__pa() cannot be used on percpu pointers because they may be
virtually mapped. Use per_cpu_ptr_to_phys() instead.
This fixes a boot crash on a some 32-bit configurations. I assume
this is related to which allocation strategy is chosen by the percpu
core.
