No stub is needed.  kvm_dirty_ring_check_request() isn't called from common code,
and should not (and isn't unless I'm missing something) be called from arch code
unless CONFIG_HAVE_KVM_DIRTY_RING=y.

x86 and arm64 are the only users, and they both select HAVE_KVM_DIRTY_RING
unconditionally when KVM is enabled.
