vdpa/ifc: fix vhost message size check

Browse Source 
For vhost message VHOST_USER_GET_CONFIG, we do not check
payload size in vhost lib, we check payload size in driver
specific ops.
For ifc vdpa driver, we just need to make sure payload size
is not smaller than sizeof(struct virtio_blk_config).

Fixes: 856d03bcdc ("vdpa/ifc: add block operations")
