Subject: [patch net-next 1/3] bnxt: simplify cls_flower command switch and handle default case

From: Jiri Pirko <jiri@...lanox.com>

Currently the default case is not handled, which with future command
introductions would introduce a warning. So handle it and make the
switch a bit simplier removing unneeded "rc" variable.
