openvswitch: drop unneeded BUG_ON() in ovs_flow_cmd_build_info()
All the callers of ovs_flow_cmd_build_info() already deal with error return code correctly, so we can handle the error condition in a more gracefull way. Still dump a warning to preserve debuggability. v1 -> v2: - clarify the commit message - clean the skb and report the error (DaveM) Fixes: ccb1352e76cf ("net: Add Open vSwitch kernel components.")
