    gensec: Change log level for message when obtaining PAC from gss_get_name_attribute failed
    
    This is the second part for the issue from commit 8bb4fccd. A KDC that
    does not return a PAC first triggers this message, then the "resorting
    to local user lookup" one. Change the log level for the "obtaining PAC
    via GSSAPI gss_get_name_attribute" message as well to avoid spamming the
    logs during normal usage. While changing this message, also remove the
    discard_const since it is no longer required.
