    fs: Export symbols replace_fd() and create_pipe_files()
    
    Need to create a pipe for usermodehelper from SCST.
    User helper will read SCSI persistent reservations
    from pipe and sync it with other nodes in cluster.
    Kernel also will read new persistent reservations
    from userspace by invoking helper with pipe.
    
    Required for https://pmc.acronis.com/browse/VSTOR-10187
