    net/mlx5: allow MTU mismatch for running shared Rx queues
    
    Previously, mlx5_shared_rxq_match() rejected any MTU mismatch between
    a port and the shared RX queue, even when the queue hardware was already
    running. This caused failures when hot-adding representors after runtime
    MTU changes (new port has default MTU=1500, but running queue was created
    with MTU=9000). It also prevented proper port reconfiguration scenarios.
    
    The fix allows MTU mismatches when rxq_ctrl->obj != NULL (queue is
    running), since runtime MTU changes via rte_eth_dev_set_mtu() only update
    software bookkeeping without recreating hardware resources. Stopped queues
    still enforce MTU matching to trigger proper reconfiguration.
    
    This patch also removes the redundant priv->mtu field and uses
    dev->data->mtu consistently for MTU tracking throughout the driver.
    
    Fixes: 4414eb800708 ("net/mlx5: store MTU at Rx queue allocation time")
    Fixes: 09c2555303be ("net/mlx5: support shared Rx queue")
