afs_osi_TraverseProcTable is a noop when working keyring support is
detected. This is why GCPAGs ends up appearing to be disabled. When
keyrings are used, pag garbage collection should not be needed, as pags
should be discarded as soon as they are unreferenced (via the destroy
callback on the afs key object) Clearly there is some problem though....
