LU-13814 clio: add cio_dio_submit

Add cio_dio_submit method and push it down in to the lov
layer.

Note this part of the series relies on the slightly clever
fact that there is no vvp method for this and the LOV
method calls the OSC method.  This lets us do setup and
teardown of the queue in the lov layer.

The next step is to push the queue handling through this
function to the cl_io_submit_rw call here, which may be
non-trivial.
