SPML/IKRIT: opal_progress and ud_only fixes

Some MXM tls such as self, shm can comlete requests immediately.
Make sure that opal_progress() is called before before request
is completed.

fix ud_only logic when hw rdma channel is using ud and main
transport is rc or dc.
(cherry picked from commit 0755a59)
