On AMD, the state of the VMCB is undefined after a shutdown VMEXIT. KVM
takes a very conservative approach to that and resets the guest altogether
when that happens. This causes the set_memory_region_test to fail
because the RIP is 0xfff0 (the reset vector). Restrict the RIP test
to KVM_EXIT_INTERNAL_ERROR in order to fix this.

This patch introduces test_add_max_memory_regions(), which checks
that a VM can have added memory slots up to the limit defined in
KVM_CAP_NR_MEMSLOTS. Then attempt to add one more slot to
verify it fails as expected.

Make set_memory_region_test available on all architectures by wrapping
the bits that are x86-specific in ifdefs. A future testcase
to create the maximum number of memslots will be architecture
agnostic.
