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. vhost-user-vsock reads the whole config
4. on realize we don't do any checks on retrieved config, so no reason
to care here
Comment "valid for resize only" exists since introduction the whole
hw/block/vhost-user-blk.c in commit
00343e4b54
"vhost-user-blk: introduce a new vhost-user-blk host device",
seems it was just an extra limitation.
Also, let's notify guest unconditionally:
1. So does vhost-user-vsock
2. We are going to reuse the functionality in new cases when we do want
to notify the guest unconditionally. So, no reason to create extra
branches in the logic.
