    igb(4): Remove disconnected SYSCTL
    
    The global hw.igb.rx_process_limit knob never was adhered to by the
    in-tree version of this driver but similar functionality is available
    via the device-specific dev.igb.N.iflib.rx_budget.
    
    While at it, remove the - besides initialization of tx_process_limit -
    unused {r,t}x_process_limit members.
