octeontx2-pf: check DMAC extraction support before filtering

Currently, configuring a VF MAC address via the PF (e.g., 'ip link
set <pf> vf 0 mac <mac>') blindly attempts to install a DMAC-based
hardware filter. However, the hardware parser profile might not
support DMAC extraction.

Check if the hardware parsing profile supports DMAC extraction
before adding the filter. Additionally, emit a warning message
to inform the operator if the MAC filter installation fails due
to missing DMAC extraction support. Update config->mac only
after hardware programming succeeds in otx2_set_vf_mac().
