The MLX5 PMD maintains 2 lists for Rx queues:
- mlx5_priv::rxqsctrl - for non-shared and shared Rx queues
- mlx5_dev_ctx_shared::shared_rxqs - for shared Rx queues only

The PMD used the `rxqsctrl` as the primary list for Rx queues
maintenance.

The PMD wipes out port mlx5_priv object after an application closed
the port.

If PMD shared Rx queues between the transfer proxy port and
representor ports and closed the transfer proxy port before
representor, the representor port cannot iterate its shared Rx queues
because Rx queues list head was wiped out.

The patch separates Rx queue storage list according to the list type:
- shared Rx queues are stored in the `shared_rxqs` only
- non-shared Rx queues are stored in the `rxqsctrl` list only.
