net/i40e: set VF MAC from PF

Support setting VF MAC address from PF.
User can call the API on PF to set a specific
VF's MAC address.

PF should set MAC address before VF initialized,
if PF sets the MAC address after VF initialized,
new MAC address won't be effective until VF
reinitialized.

This will remove all existing MAC filters.
