Xueming Li e867144b73 vhost-user: remove VirtQ notifier restore ... Notifier set when vhost-user backend asks qemu to mmap an FD and offset. When vhost-user backend restart or getting killed, VQ notifier FD and mmap addresses become invalid. After backend restart, MR contains the invalid address will be restored and fail on notifier access. On the other hand, qemu should munmap the notifier, release underlying hardware resources to enable backend restart and allocate hardware notifier resources correctly. Qemu shouldn't reference and use resources of disconnected backend. This patch removes VQ notifier restore, uses the default vhost-user notifier to avoid invalid address access. After backend restart, the backend should ask qemu to install a hardware notifier if needed.
