Florian Fainelli 90a86d00af net: dsa: bcm_sf2: Do not assume DSA master supports WoL ...

[ Upstream commit c3152ec4c0 ]

We assume in the bcm_sf2 driver that the DSA master network device
supports ethtool_ops::{get,set}_wol operations, which is not a given.
Avoid de-referencing potentially non-existent function pointers and
check them as we should.
