    cred: proc_set_cred(): Remove obsolete comments
    
    These have been obsoleted since they were first written (in commit
    "cred: add proc_set_cred helper", daf63fd2f9a8d040, r280130) by some
    subsequent commits ("proc: refactor clearing credentials into
    proc_unset_cred", 5a90435ccfed8e1e, r361448; "cred: distribute reference
    count per thread", 1724c563e62fa800, r361993).
    
    No functional change.
