KVM: x86: Rename kvm_x86_ops' gmem_invalidate() to gmem_make_shared()

Browse source

Rename kvm_x86_ops's gmem_invalidate() hook to gmem_make_shared(), as the
hook doesn't invalidate anything, and so that KVM doesn't need to add yet
another vendor callback to support "convert to shared" once in-place
conversion comes along.

Opportunistically wrap the ops declarations with a GMEM_RECLAIM guard so
that attempting to wire up a .gmem_make_shared() hook without selecting
CONFIG_HAVE_KVM_ARCH_GMEM_RECLAIM will result in a build failure.

No functional change intended.
