[PATCH 1/4] coccicheck: propagate error and stop processing after first error

Propagate back in the shell Coccinelle's error. Also stop processing if an error has occured. This lets us handle some errors in coccinelle cocci files and if they bail out we should inspect the errors. This will be more useful later to help annotate coccinelle version dependency requirements.
