i40e: delete filter after adding its replacement when converting

Fix a subtle issue with the code for converting VID=-1 filters into VID=0
filters when adding a new VLAN. Previously the code deleted the VID=-1
filter, and then added a new VID=0 filter. In the rare case that the
addition fails due to -ENOMEM, we end up completely deleting the filter
which prevents recovery if memory pressure subsides. While it is not
strictly an issue because it is likely that memory issues would result
in many other problems, we shouldn't delete the filter until after the
addition succeeds.
