virtio: use correct number of entries field

Browse Source 
Socket message VHOST_USER_SET_VRING_ENABLE will use number of
vring entries as input parameter to indicate the vring is
enabled or not, previously the flag in vhost-user library
wasn't checked before commit d0fcc38f5
"vhost: improve device readiness notifications", so here
we also use correct filed set in SPDK.

Fix issue #1583.
