lint: only skip 'unused' warnings after errors, not other warnings
Previously, in -w mode, any warning suppressed further 'unused' warnings, even though there was no need to do that. This can be seen in the test gcc_attribute_var.c, where only the last unused variable from a function was marked as unused, the others slipped through. Fixed by counting the errors and the warnings separately and only combining them if actually desired.
