Thomas Huth 642ba89672 hw/i386/intel_iommu: Fix endianness problems related to VTD_IR_TableEntry ... The code already tries to do some endianness handling here, but currently fails badly: - While it already swaps the data when logging errors / tracing, it fails to byteswap the value before e.g. accessing entry->irte.present - entry->irte.source_id is swapped with le32_to_cpu(), though this is a 16-bit value - The whole union is apparently supposed to be swapped via the 64-bit data[2] array, but the struct is a mixture between 32 bit values (the first 8 bytes) and 64 bit values (the second 8 bytes), so this cannot work as expected. Fix it by converting the struct to two proper 64-bit bitfields, and by swapping the values only once for everybody right after reading the data from memory.
