vhost-user-blk: simplify and fix
Here we just prepare for the following patch, making possible to report
GenericError as recommended.
This patch doesn't aim to prevent further use of DeviceNotFound by
future interfaces:
- find_device_state() is used in blk_by_qdev_id() and qmp_get_blk()
functions, which may lead to spread
Send a new event when guest reads virtio-pci config after
virtio_notify_config() call.
That's useful to check that guest fetched modified config, for example
after resizing disk backend.

Add command to sync config from vhost-user backend to the device. It
may be helpful when VHOST_USER_SLAVE_CONFIG_CHANGE_MSG failed or not

by vhost-user server).
Command result is racy if allow it during migration. Let's allow
Let's not care about what was changed and update the whole config,
reasons:
1. config->geometry should be updated together with capacity, so we fix
a bug.
2. Vhost-user protocol doesn't say anything about config change
limitation. Silent ignore of changes doesn't seem to be correct.
3.

Actually that's a false-positive.. Compiler can't believe that body of
WITH_JOB_LOCK_GUARD() will be executed
I noticed the issue in the commit message 'ffvat' should be 'vvfat',
I'll fix it in the next version.
