Fore-commit(c6beefd674) only saves features of queue0,
this makes wrong features of other queues in multiqueues
situation.
For examples:
qemu-system-aarch64 ... \
-chardev socket,id=charnet0,path=/var/run/vhost_sock \
-netdev vhost-user,chardev=charnet0,queues=2,id=hostnet0 \
...
There are two queues in nic assocated with one chardev.
When chardev is reconnected, it is necessary to save and
restore features of all queues.
