octeon_ep: fix VF MAC address lifecycle handling
Currently, VF MAC address info is not updated when the MAC address is configured from VF, and it is not cleared when the VF is removed. This leads to stale or missing MAC information in the PF, which may cause incorrect state tracking or inconsistencies when VFs are hot-plugged or reassigned. Fix this by: - storing the VF MAC address in the PF when it is set from VF - clearing the stored VF MAC address when the VF is removed This ensures that the PF always has correct VF MAC state.
