cciss: fix regression firmware not displayed in procfs

commit 22bece00dc1f28dd3374c55e464c9f02eb642876 upstream

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.
