cciss: fix regression firmware not displayed in procfs
This regression was introduced by commit
6ae5ce8e8d4de666f31286808d2285aa6a50fa40 ("cciss: remove redundant code").
This patch fixes a regression where the controller firmware version is not
displayed in procfs. The previous patch would be called anytime something
changed. This will get called only once for each controller.
