[1/9] media: vim2m: Try to schedule a m2m device run on request submission

Commit Message

In the most basic use scenario, where only one output and one capture
buffers are queued and the request is submitted, there is no provision
to try to schedule a m2m device run.

This adds the appropriate call to the vim2m_request_submit so that it
can start in that scenario.
