Heiner Kallweit 596690e9f4 ethtool: return error from ethnl_ops_begin if dev is NULL ...

Julian reported that after d43c65b05b Coverity complains about a
missing check whether dev is NULL in ethnl_ops_complete().
There doesn't seem to be any valid case where dev could be NULL when
calling ethnl_ops_begin(), therefore return an error if dev is NULL.

Fixes: d43c65b05b ("ethtool: runtime-resume netdev parent in ethnl_ops_begin")
