drivers/virtio: fix duplicate naming of include guard

  The LGTM static code analysis tool is reporting

"The macro name '_VHOST_NET_USER_H' of this include guard is used
in 2 different header files."

lib/librte_vhost/vhost_user.h has the same include guard.
Renamed the include guard in vhost.h to differentiate.

Above two files are private headers in two individual modules,
there is no chance that they will be included by the same file.
But I agree it's not a good name for any of them.

If we want to change it, I prefer to change it to _PATH_NAME_,
e.g. _VIRTIO_USER_VHOST_H_ or similar.
