While we're at it, remove some code which has never been invoked.
Keep the comment though, as it seems potentially half useful.
Fixes the following W=1 kernel build warning(s):
drivers/net/fddi/skfp/cfm.c: In function ‘cfm’: drivers/net/fddi/skfp/cfm.c:211:6: warning: variable ‘oldstate’ set but not used [-Wunused-but-set-variable]
