qcacld-3.0: Donnot send vdev delete via serialization

Presently vdev delete is sent via serialization, which
needs a vdev reference. With the new FR to send the
vdev delete on the physical destroy in object manager
vdev delete cannot be sent via serialization.

Hence, disable the serialization for the vdev and
donot send the vdev delete via serialization.
