    common/mlx5: fix shared mempool subscription
    
    MLX5 PMD counted each mempool subscribe invocation. The PMD expected
    that the mempool subscription will be deleted after the mempool
    counter dropped to 0. However, current PMD design unsubscribes mempool
    callbacks only once.
    As the result, the PMD destroyed mlx5_common_device but kept
    shared RX subscription callback. EAL tried to activate that callback
    and crashed.
    
    The patch removes mempool subscriptions counter.
    The PMD registers mempool subscription once only. An attempt
    to register existing subscription returns EEXIST.
    Also, the PMD expects to remove subscription when mempool unsubscribe
    was activated.
