vhost_task: fix vhost_task_create() documentation

Commit cb38090 ("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.
