KVM: arm64: selftest: Add the missing .guest_prepare()
Running page_fault_test on a Cortex A72 fails with
Test: ro_memslot_no_syndrome_guest_cas
Testing guest mode: PA-bits:40, VA-bits:48, 4K pages
Testing memory backing src type: anonymous

guest_check_lse()
because we don't have a guest_prepare stage to check the presence of
FEAT_LSE and skip the related guest_cas testing, and we end-up failing in
GUEST_ASSERT(guest_check_lse()).
Add the missing .guest_prepare() where it's indeed required.
