openvswitch: drop unneeded BUG_ON() in ovs_flow_cmd_build_info()
[ Upstream commit 8ffeb03fbba3b599690b361467bfd2373e8c450f ]
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.")
