[PATCH net-next 09/15] net/mlx5: Rename and move mlx5_esw_query_vport_vhca_id

From: Akiva Goldberger <agoldberger@nvidia.com>

Rename mlx5_esw_query_vport_vhca_id to mlx5_vport_get_vhca_id and move
it to vport file. Also, add function declaration to mlx5_core header
file. This better represents the function's usage and allows for it to
be called from other parts of the mlx5_core driver.
