    igb: PCIe devices do not need to unset MANC_ARP_ENA
    
    Users reported that ARP's were lost with igb. The problem
    is fixed by not enabling this manageability configuration
    bit.
    
    None of the release_manageability code is actually needed as the
    normal device reset during a shutdown returns everthing to
    the right condition automatically.
