i40e/i40evf: clean up error messages

Browse Source 
Clean up and enhance error messages related to VF MAC/VLAN filters.
Indicate which VF is having issues, and if possible indicate the MAC
address or VLAN involved.

Also, when an error is returned from the PF driver, print useful
information about what went wrong, for the most likely cases.
