[PULL 53/54] hw/vhost-user-scsi|blk: set `supports_config` flag correctly

[Michael S. Tsirkin]

From: Changpeng Liu <changpeng.liu@intel.com>

Currently vhost-user-scsi driver doesn't allow to change
the configuration space of virtio_scsi, while vhost-user-blk
support that, so here we set the flag in vhost-user-blk driver
and unset it in vhost-user-scsi.
