Subject: [PATCH net-next 2/2] openvswitch: Fix overreporting of drops in dropwatch

Currently queue_userspace_packet will call kfree_skb for all frames,
whether or not an error occurred. This can result in a single dropped
frame being reported as multiple drops in dropwatch. This patch will
consume the skbs instead.
