RMM v1.0 provides no mechanism for the host to perform debug operations
on the guest. So don't expose KVM_CAP_SET_GUEST_DEBUG and report 0
breakpoints and 0 watch points.

Changes since v7:
  * Remove the helper functions and inline the kvm_is_realm() check with
    a ternary operator.
  * Rewrite the commit message to explain this patch.
