[SRU][N:linux-bluefield][PATCH v1 04/10] net/mlx5: Rename and move mlx5_esw_query_vport_vhca_id

[Stav Aviram]

From: Akiva Goldberger <agoldberger at nvidia.com>

BugLink: https://bugs.launchpad.net/bugs/2126876

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.
