vhost: vhost_user.c code cleanup

This patchesries introduces a set of code redesigns in vhost_user.c.

The goal is to unify and simplify vhost-user message handling. The
patches do not intend to make any functional changes.

v3 changes:
 - rebased on top of git://dpdk.org/next/dpdk-next-virtio dead0602
 - introduce VH_RESULT_FATAL (Maxime Coquelin)
 - vhost_user_set_features return VH_RESULT_FATAL on failure.
   This allows keeping the propagate error logic (Ilya Maximets)
 - fixed vhost_user_set_vring_kick and vhost_user_set_protocol_features
   return VH_RESULT_ERR upon failure
 - fixed missing break in case VH_RESULT_ERR (Ilya Maximets)
 - fixed a type on the description of 2/5 patch (Maxime Coquelin)

v2 changes:
 - Fix the comments by Tiwei Bie
 - Keep the old behavior
   - Fall through when the callback returns VH_RESULT_ERR
   - Fall through if the request is out of range
