[PATCH] virtio: Fix various coding style issues

[Juan José Arboleda]

Address various coding style warnings in the virtio_mmio driver:

- Move trailing `*/` to a new line in block comments.
- Use parentheses with sizeof for consistency.
- Add missing blank line after declarations.
- Replace 'S_IRUSR' with '0400' for permissions.
