    Fix SPNEGO acceptor mech filtering
    
    Commit c2ca2f26eaf817a6a7ed42257c380437ab802bd9 (ticket 8851)
    accidentally changed the SPNEGO acceptor code to filter mechanisms by
    the obtainability of initiator credentials rather than acceptor
    credentials, when the default acceptor credential is used.
    
    (cherry picked from commit e25918cb9efd7361aa78d2d96cd097dd34fdf35d)
    
    ticket: 8908
    version_fixed: 1.18.2
