[cogl] Don't use the label 'ERROR' because it conflicts with windows.h

[Neil Roberts <nroberts src gnome org>]

    Don't use the label 'ERROR' because it conflicts with windows.h
    
    wingdi.h which gets included from windows.h #defines ERROR to 0 so we
    can't use it as a label in Cogl. This patch changes it to be error in
    lower case instead.
