[PATCH v2 09/15] net/iavf: pack structures when building with MSVC

[Tyler Retzlaff]

Add __rte_msvc_pushpack(1) to all __rte_packed structs to cause packing
when building with MSVC.

Remove __rte_packed where it appears natural alignment without
packing would produce the same layout or the struct is internal.
