qcacmn: Replace session_id in gateway_update_req_param

In struct gateway_update_req_param the legacy identifier session_id is
currently used to identify the vdev of interest. To align with the
converged nomenclature rename this to vdev_id.

This is co-dependent with I2d24a54e80931a944580e968a841679d2da7b2a1
("qcacld-3.0: Use vdev_id in gateway_update_req_param").

Change-Id: I84b28aa734b570f0a7834fbac7d27e9c66b8b026
CRs-Fixed: 2404012
