    net/ixgbe: fix queue received bytes CRC adjustment
    
    For 82599, QBRC is a 36-bit clear-on-read counter, while
    QPRC is a 32-bit clear-on-read counter. ixgbe_read_stats_registers()
    accumulates QBRC in a 64-bit software counter and, when CRC stripping
    is disabled, subtracts the CRC bytes accounted for each received packet.
    
    The CRC adjustment is computed as:
    
            delta_qprc * RTE_ETHER_CRC_LEN
    
    Since delta_qprc is 32-bit, the multiplication is performed in 32 bits
    and may wrap before the result is subtracted from the 64-bit QBRC
    accumulator. A full 32-bit packet delta needs more than 32 bits to
    represent the CRC-byte adjustment.
    
    Cast delta_qprc to uint64_t before the multiplication so the adjustment
    is computed with the same effective width as the byte counter.
    
    Found by Linux Verification Center (linuxtesting.org) with SVACE.
