My previous patch caused a slight code size increase when DEBUG_FS is disabled,
as Stanislaw Gruszka pointed out.

Fix this with an added IS_ENABLED() check.

Fixes: cf6b9ba172dd ("wifi: iwlegacy: don't warn for unused variables with DEBUG_FS=n")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Ideally this would be folded into my original fix. If that's not possible,
please apply on top.
