    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

    v1 -> v2:
     - clarify the commit message
     - clean the skb and report the error (DaveM)
