    auth: Fix GetNthIdentityOrUser EOF return code
    
    Before commit 0af17e7e, afsconf_GetNthUser always returned 1 on
    failure, to indicate to the caller that they should stop traversing
    over the list. After commit 0af17e7e, when reaching the end of the
    list, we return EIO or -1. This causes 'bos listusers' invocations to
    always fail, since 'bos' clients expect to get the code 1 when
    reaching the end of the SUsers list.
    
    To fix this, make GetNthIdentityOrUser always return -1 when searching
    beyond the end of the list. For the newer interface
    afsconf_GetNthIdentity, we return this as-is, to have a separate
    return code specifically for EOF, but still allowing us to return any
    positive error code in case of an error.
    
    For the older interface afsconf_GetNthUser, return 1 in this
    situation, to retain compatibility with the old interface (both at the
    libauth level and on the wire).
