i40evf: don't delete all the filters

Browse Source 
Due to an inverted conditional, the driver was marking all of its MAC
filters for deletion every time set_rx_mode was called. Depending upon
the timing of the calls to set_rx_mode and the processing of the admin
queue, the driver would (accidentally) end up with a varying number of
functional filters.

Correct this logic so that MAC filters are added and removed correctly.
Add a check for the driver's "hardware" MAC address so that this filter
doesn't get removed incorrectly.
