Currently in the i40e driver there is no implementation of different
MAC address handling depending on whether it is a legacy or primary.
Introduce new checks for VF to be able to specify its primary MAC
address based on the VIRTCHNL_ETHER_ADDR_PRIMARY type.

Primary MAC address are treated differently compared to legacy
ones in a scenario where:
1. If a unicast MAC is being added and it's specified as
VIRTCHNL_ETHER_ADDR_PRIMARY, then replace the current
default_lan_addr.addr.
2. If a unicast MAC is being deleted and it's type
is specified as VIRTCHNL_ETHER_ADDR_PRIMARY, then zero the
hw_lan_addr.addr.
