    libefivar: Fix byte orders of iSCSI.Lun
    
    Per UEFI spec, iSCSI.Lun is a 8-byte array with byte #0 in the left.
    It means "0102030405060708" should be converted to:
        UINT8[8] = {01, 02, 03, 04, 05, 06, 07, 08}
    or  UINT64 = {0807060504030201}
    
    Today's implementation wrongly uses the reversed order.
