From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>
Remove explicit calls to functions that are called ravb_open(). There is
no need to have them doubled now that the ravb_open() already contains
what is needed for the interface configuration. Along with it, PTP needed
configurations were moved to ravb_wol_restore(). With this, code in
ravb_resume() is simpler.
