KVM: selftests: Ignore KVM 5-level paging support for VM_MODE_PXXV48_4K
Explicitly set the VA width to 48 bits for the x86_64-only PXXV48_4K VM
mode instead of asserting the guest VA width is 48 bits. The fact that
KVM supports 5-level paging is irrelevant unless the selftests opt-in to
5-level paging by setting CR4.LA57 for the guest. The overzealous
assert prevents running the selftests on a kernel with 5-level paging
enabled.
Incorporate LA57 into the assert instead of removing the assert entirely
as a sanity check of KVM's CPUID output.
