openvswitch: Fix overreporting of drops in dropwatch
[ Upstream commit c21ab2afa2c64896a7f0e3cbc6845ec63dcfad2e ]
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 functions
caller may also call kfree_skb in case of an error. This patch will
consume the skbs instead and allow caller's to use kfree_skb.
