Octeontx2-af: Add programmed macaddr to RVU pfvf

Browse Source 
Octeontx2/CN10k MAC block supports DMAC filters. DMAC filters
can be installed on the interface through ethtool.

When a user installs a DMAC filter, the interface's MAC address
is implicitly added to the filter list. To ensure consistency,
this MAC address must be kept in sync with the pfvf->mac_addr field,
which is used to install MAC-based NPC rules.

This patch updates the pfvf->mac_addr field with the programmed MAC
address and also enables VF interfaces to install DMAC filters.
