KVM: selftests: Use TEST_EXTRA region in x86's smaller MAXPHYADDR test

Use the TEST_EXTRA region/memslot for x86's smaller MAXPHYADDR test instead
of a custom memslot, so that the primary vm_phy_pages_alloc() APIs can be
reworked to take a region type instead of a raw memslot.

For all intents and purposes, no functional change intended, as
vm_add_extra_mem_region() is barely more than a wrapper for
vm_userspace_mem_region_add().
