[POWERPC] spufs: save MFC command channel before purging MFC queue
During the context save process, we currently save the MFC command channel after purging the MFC queues. This causes a systemsim warning, as the command channel may be in an unknown state after the purge. This change does the save before purging the MFC queues. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
