Subject: net: switchdev: add SET_SWITCHDEV_OPS helper
Patch-mainline: v4.13-rc1
Git-commit: d643a75ac2bcc559994405d29c50ed086aeae434
References: bsc#1056787

Add a helper to allow switchdev ops to be set if NET_SWITCHDEV is configured
and do nothing otherwise. This allows for slightly cleaner code which
uses switchdev but does not select NET_SWITCHDEV.
