    Fix gss_get_mic_iov() example code
    
    The example code for gss_get_mic_iov() using a caller-provided buffer
    calls gss_wrap_iov_length() and gss_wrap_iov() instead of
    gss_get_mic_iov_length() and gss_get_mic_iov() as intended.  Reported
    by Frank Filz.
    
    (cherry picked from commit bf4156db4f6c2e8cd420cd556bfa9e39f1a3d556)
    
    ticket: 8797
    version_fixed: 1.17.1
