Subject: [PATCH] vhost: disable Waddress-of-packed-member for internal vhost
 library

When using internal vhost library, there is a warning information:
taking address of packed member of class or structure may result in
an unaligned pointer value [-Werror,-Waddress-of-packed-member].

DPDK disable this check by default, so we will do it same for
internal vhost library.
