Subject: [PATCH 2/2] scripts: coccicheck: Separate spatch stdout and stderr

This helps automating coccicheck runs by discarding stderr and only
looking at the output of stdout. In report mode the only remaining
output on stdout is the initial "Please check for false positives"
message followed by each spatch warning found.
