Maxime Chevallier 1ad84a151a net: ethtool: phy: Don't set the context dev pointer for unfiltered DUMP ...

The context info allows continuing DUMP requests, shall they fill the
netlink buffer.

In the case of filtered DUMP requests, a reference on the netdev is
grabbed in the .start() callback and release in .done().

Unfiltered DUMP request don't need the dev pointer to be set in the context
info, doing so will trigger an unwanted netdev_put() in .done().
