Change I1f668fff633a5e5cdfc478e7f619e9600930b333 ("qcacld-3.0: Use wma
callback to get vdev dp handle") removed the implementation of
pmo_ucfg_vdev_update_dp_handle(), but left behind the stub
implementation for use when PMO is disabled. This stub, since renamed
to ucfg_pmo_vdev_update_dp_handle(), is unused, so remove it.
