    Optimize redundent code fetching server of network dump
    
    Code in function kdump_install_net used to get server of network dump
    is is a little redundent, can be optimized into one line. For nfs/ssh,
    this line of code is enough.
    
    Test passed on local kvm guest with Fedora 18.
