net/mlx5: SD, keep netdev resources on same PF in switchdev mode

Browse source

In SD switchdev mode, network device resources such as channels and
completion vectors must remain on the same PF rather than being
distributed across SD group members.

Modify mlx5_sd_ch_ix_get_dev_ix() to return 0 and
mlx5_sd_ch_ix_get_vec_ix() to return the channel index directly when
in switchdev mode, keeping resources local to the requesting PF.
