iavf: fix err handling for MAC replace

Browse source

Defer removal of current primary MAC until a replacement is successfully
added. Previous implementation would left filter list with no primary MAC.
This was found while reading the code.

The patch takes advantage of the fact that there can only be a single primary
MAC filter at any time ([1] by Piotr)

Piotr has also applied some review suggestions during our internal patch
submittal process.
