Fix code style related to including header file. Include header files
before declaring macro definitions to avoid conflicts.

Which conflicts? These macros are there precisely to change
how the header behaves.


Hi Michael
     I think including the header files should be placed before the macro
definition.
     If VIRTIO_PCI_NO_LEGACY and VIRTIO_RING_NO_LEGACY are needed for control
header file, we should put them at the beginning of virtio_pci_common.h.

What do you think?

I think you should read the code in question not make guesses.

Okey. I see, thx
