net: ethtool: phy: Check the req_info.pdn field for GET commands
When processing the netlink GET requests to get PHY info, the req_info.pdn
pointer is NULL when no PHY matches the requested parameters, such as when
the phy_index is invalid, or there's simply no PHY attached to the
interface.
Therefore, check the req_info.pdn pointer for NULL instead of
dereferencing it.
