Subject: mlxsw: spectrum_flower: Do not stop at FLOW_ACTION_PRIORITY
Patch-mainline: v5.7-rc1
Git-commit: 0be0ae144109a43266631b94adef5c806c56a4b1
References: bsc#1176774

The handler for FLOW_ACTION_PRIORITY ends by returning whatever the
lower-level function that it calls returns. If there are more actions lined
up after this action, those are never offloaded. Fix by only bailing out
when the called function returns an error.
