    net/ixgbe: fix good octets CRC adjustment
    
    On some devices, such as 82599, GORC is a 36-bit clear-on-read counter,
    while GPRC is a 32-bit clear-on-read counter.
    ixgbe_read_stats_registers() accumulates GORC in a 64-bit software
    counter and, when CRC stripping is disabled, subtracts the CRC bytes
    accounted for each received packet.
    
    The driver does not read GPRC directly. Due to an erratum, it derives
    the good packet delta from the sum of per-queue packet receives instead.
    The 32-bit QPRC registers are used for this purpose.
    
    delta_gprc is used as an accumulator for those per-queue deltas and is
    then used to compute the CRC-byte adjustment. Keeping it 32-bit may wrap
    the accumulated packet delta before it is used to adjust the 64-bit GORC
    counter.
    
    Make delta_gprc 64-bit so the accumulated packet delta and the CRC-byte
    adjustment are computed without 32-bit overflow.
    
    Found by Linux Verification Center (linuxtesting.org) with SVACE.
