LU-10729 tests: replay-dual/23d to wait

replay-dual/23d simulates a dropped reply for the executed
update, but previous tests can break this:
 - the update modifies remote llog
 - there can be another uptdate to that remote log
   (from the previous tests)
 - fail_loc (OBD_FAIL_UPDATE_OBJ_NET) is applied to the
   old update
 - the 23d's update gets stuck

so the test has to ensure there is no pending/in-flight
updates.
