OCC: Do not call occ_do_load if hostservice LID load is not complete
OCC: Do not call occ_do_load if hostservice LID load is not complete

Commit 4db0c1e4f introduced occ_load_req queue. With that changes we queue
the occ load request if hostservice LID load is not complete. And we have
callback function (occ_poke_load_queue)...which takes care of calling
__occ_do_load().

But current code proceeds and calls __occ_do_load() after queueing....which
is not correct. So just return if we queue the occ load request.
