net/mlx5: Move vport DOWN state check out of mlx5_query_vport_max_tx_speed()
mlx5_query_vport_max_tx_speed() was introduced to serve the
query_port_speed path, which uses max_tx_speed == 0 when port is down.
This is incorrect for callers that need the actual configured speed
regardless of vport state, such as modify-vport-state helpers
that must preserve the speed across state transitions.
Move this logic to the caller function in the verb flow and let
mlx5_query_vport_max_tx_speed() return the raw firmware value
unconditionally.
Fixes: aaecff5e13cd ("RDMA/mlx5: Implement query_port_speed callback")
