qa/upgrade: conditionally disable update_features tests

with the recent support for async rbd operations from pacific+ when an
    older client(non async support) goes on upgrade, and simultaneously
    interacts with a newer client which expects the requests to be async,
    experiences hang; considering the return code for request completion to
    be acknowledgement for async request, which then keeps waiting for
    another acknowledgement of request completion.

    this if happens should be a rare only when lockowner is an old client
    and should be deferred if compatibility issues arises.
