In BE architecture, HW provides basic vdev stats support for upto
48 vdevs. For each vdev, there is vdev_stats_id which represents the
id of this vdev on HW. This vdev_stats_id is assigned by host and
is conveyed to FW at the time of vdev creation in wmi_vdev_create_cmd.
FW uses this vdev_stats_id to fetch the stats from HW.
Add logic to convey vdev_stats_id to FW at the time of vdev create.
