    ixgbe: Avoid signed overflow in LED register masks
    
    LED index three shifts the blink bit into bit 31.  Convert the base to
    the register width before shifting so the operation is unsigned.
    
    This is the ixgbe counterpart of the e1000 correction imported from
    DPDK commit 214cb0d7f1.
    
    (cherry picked from commit bbdd3c4692e2869817f77c359b4a2719e716921d)
