A RAM device represents a mapping to a physical device, such as to a PCI
* MMIO BAR of an vfio-pci assigned device.
Vhost listens to this region,and increases the region's reference count
while passthrough?for?network adapters (Physical Function, PF or Virtual
Function, VF).
After detaching network adapters with vhost backend dirver or vhost user
dirver,
it unregister vhost listen function by memory_listener_unregister.
After detaching the passthrough pf or vf,
the RAM device region's reference by vhost listener increated can not be
released,
due to vhost listen function does not exist.So let's just skip RAM device
memory.
