    nfs/nlm: handle reconnect for non-NLM4_LOCK requests

    When a reply on an NLM-procedure gets stuck, the NFS-client will resend
    the request. This can happen through a re-connect in case the connection
    was terminated (long delay in the reply on the initial request). Once
    that happens, not all NLM-procedures are handled correctly.

    Testing this is difficult and time-consuming. There still may be
    problems with certain operations, but this definitely makes it behave
    much better than before.

    The problem occured due to a problem in EC, change-id I18a782903ba
    addressed the root cause.
