i have been tested many times,i confirm ram device region references is not be
dropped,when detaching vhost net.
So far ，i do not have better idea to drop the references. the ram device
momery is special .
i think vhost listening the RAM devicemomery is not necessary. skip RAM device
mem
i'm sorry ，it should be memory_region_is_ram_device in new version qemu ,
memory_region_is_skip_dump is in older version qemu.
