qcacld-3.0: Alias vdev_id to session_id in hdd_adapter

Currently struct hdd_adapter uses the legacy term session_id. To align
with converged naming it is desirable to change this to vdev_id, but
due to the large number of places where session_id is used it will be
difficult to modify all occurences at once. In order to allow changes
to "trickle in" replace the session_id field with a union that
contains both a session_id and a vdev_id field. This will allow
vdev_id and session_id to both be used to access the same data item.

Subsequent changes can then replace references to session_id with
vdev_id, and then once all references have been converted, replace the
union with a single vdev_id field.
