s4:torture/smb2/session: invalidate credential cache

Invalidate credential cache before connecting to the server, otherwise
we will reuse the credentials from the credential cache populated by the
preceeding tests.

Also invalidate it at the end, otherwise subsequent tests might run into
problems if the credentials expire while authenticating.
