vhost-user-test: small changes to init_hugepagefs 

After the conversion to qgraph, the equivalent of "main" will be in
a constructor and will run even if the tests are not being requested.
Therefore, it should not assert that init_hugepagefs succeeds and will
be called when creating the TestServer.  This patch changes the prototype
of init_hugepagefs, this way the next patch looks nicer.
