Raphael Norwitz b906a23c33 libvhost-user: prevent over-running max RAM slots ... When VHOST_USER_PROTOCOL_F_CONFIGURE_MEM_SLOTS support was added to libvhost-user, no guardrails were added to protect against QEMU attempting to hot-add too many RAM slots to a VM with a libvhost-user based backed attached. This change adds the missing error handling by introducing a check on the number of RAM slots the device has available before proceeding to process the VHOST_USER_ADD_MEM_REG message.
