[dpdk-dev] [PATCH v4 20/22] vhost: workaround the build dependency on mbuf header

rte_mbuf struct is something more likely will be used only in vhost-user
net driver, while we have made vhost-user generic enough that it can
be used for implementing other drivers (such as vhost-user SCSI), they
have also include <rte_mbuf.h>. Otherwise, the build will be broken.

We could workaround it by using forward declaration, so that other
non-net drivers won't need include <rte_mbuf.h>.
