Why keep two mechanisms (and two potential code paths to maintain)
when the only way vhost_wq_init() can fail is if out of memory.
You may have needed the messages and this during development but for
the final version just do it one way.
If alloc_workqueue fails, then the net_init function should propogate
the error code and fail as well.
