vhost_task: fix vhost_task_create() documentation

Commit cb380909ae3b ("vhost: return task creation error instead of NULL")
changed the return value of vhost_task_create(), but did not update the
documentation.

Reflect the change in the documentation: on an error, vhost_task_create()
returns an ERR_PTR() and no longer NULL.
