This reverts commit 10a06fd65f667a972848ebbbcac11bdba931b544.

Dataplane has used the same virtqueue code as non-dataplane since
commits e24a47c5b73e04f94030e2daa356c7582aebfca2 ("virtio-scsi: do not
use vring in dataplane") and 03de2f527499ae0c6d16a379665d072345254f2c
("virtio-blk: do not use vring in dataplane").  It is no longer
necessary to stop dataplane in order to sync state since there is no
duplicated virtqueue state.
