LU-4086 tests: strengthen sanity-hsm/test_33

Instead of waiting+checking both Restore and Cancel HSM operations
sequentially, wait for both to be finished and then check each
results. This will allow to handle conditions where Restore
terminates before the Cancel is started.

Also added to wait_all_done() the capability to only work on
requests for a specific fid.
