So, if it fails and we return right\naway, the skb ends up leaked.\n\nFix that by breaking instead and letting the common error handling\ncode at the bottom of the loop to free the skb properly.\n\nThis is a very unlikely scenario as it requires the packet to become\nunparseable by applying a set of actions on a previously parseable skb,\nbut should be fixed nevertheless.\n\nReported by Sashiko."
