Peter Grehan 2136849868 Fix pci-passthru MSI issues with OpenBSD guests
- Return 2 x 16-bit registers in the correct byte order
 for a 4-byte read that spans the CMD/STATUS register.
  This reversal was hiding the capabilities-list, which prevented
 the MSI capability from being found for XHCI passthru.

- Reorganize MSI/MSI-x config writes so that a 4-byte write at the
 capability offset would have the read-only portion skipped.
  This prevented MSI interrupts from being enabled.
