[cifs-utils PATCH 9/8] cifs.upcall: use a MEMORY: ccache when instantiating from a keytab

[Jeff Layton]

Using a more permanent ccache is potentially problematic when we're
instantiating a new one. We might be operating under different creds
than expected. Just use a MEMORY: ccache since we don't need it to
last longer than the life of the upcall anyway.
