    common/mlx5: adjust fork call with the new kernel API
    
    While doing process fork() the operating system remaps all the parent
    process's memory to the address space of the child process and activates
    the Copy-on-Write mechanics - it duplicates physical pages once memory
    writing happens in the child process. Sometimes memory duplication is
    not allowed - for example, if the page contains hardware queue
    descriptors. To handle similar issues the rdma-core library should be
    prepared for forking.
    
    The ibv_fork_init() prepares the library to track all the related memory
    and prevent it from forking using madvise() system API. This approach
    allows fork, but not all the memory is forked to the child process and,
    application should care not to touch pages where the parent application
    allocated the rdma-core objects.
    
    The newer kernels propose an option of copy-on-fork for DMA pages and
    tracking all the memory and disabling it for the forking is no longer
    needed. The new API routine ibv_is_fork_initialized() should be involved
    to decide if library initialization for forking is required.
