ethtool: pse-pd: fix missing ethnl_ops_complete()

Browse Source 
pse_prepare_data() is missing ethnl_ops_complete() if
ethnl_req_get_phydev() returned an error. Move getting
phydev up so that we don't have to worry about this
(similar order to linkstate_prepare_data()).

Note that phydev may still be NULL (this is checked in
pse_get_pse_attributes()), the goal isn't really to avoid
the _begin() / _complete() calls, only to simplify the error
handling.

While at it propagate the original error. Why this code
overrides the error with -ENODEV but !phydev generates
-EOPNOTSUPP is unclear to me...
