    vos: Restore some VNOVOL error messages
    
    Many places in vos/vsprocs have code to delete a volume. Commit
    f4e73067cdef990262c69c38ac98761620a63f25 tried to refactor them by
    consolidating the common "delete" code into DoVolDelete. However, not
    all of the removed code had exactly the same behavior, and some of
    these variants were not handled by DoVolDelete.
    
    One such variation is that DoVolDelete always printed an error message
    if the target volume did not exist. But for some call sites this
    condition is not an error, and prior to the refactoring they did not
    print such an error message. Commit
    1092cbe34fc8519826b3fa0565505b7bd81bc922 tried to correct this by
    suppressing the error message if the target volume does not exist.
    However, this means that all DoVolDelete calls do not print such an
    error, where some should and some should not print an error. This
    means that in some edge cases when we encounter an unexpected VNOVOL
    error, we now skip printing the specific error we got and instead go
    right to cleanup/recovery/exit. For a few other cases, we used to
    print an error and continue (because it is a non-fatal error or a
    warning), but now we print nothing when we encounter a VNOVOL error.
    
    Fix this by specifically printing an error for the VNOVOL error for
    DoVolDelete call sites that used to print such an error. Do this for
    all such sites except ones where we obviously print an error
    immediately afterwards anyway.
    
    This is just a quick targeted fix. A future more robust fix should
    involve altering DoVolDelete to handle all of the different behaviors
    expected by its various callers.
