vhost: close remaining memory region FDs during backend cleanup

Browse Source 
After changes done in commit f325e71c, closing old FD is delayed until
VHOST_USER_SET_VRING_ADDR. If VM is closed before this call, original FDs
remain during vhost_backend_cleanup. This resolves issue #162.

This patch closes second set of FDs during vhost backend cleanup.
