This is a bit confusing. Factor this out into ice_ptp_rebuild_owner() instead. The ice_ptp_reset() function is called by ice_rebuild() to restore PTP functionality after a device reset. Follow the convention set by the ice_main.c file and rename this function to ice_ptp_rebuild(), in the same way that we have ice_prepare_for_reset() and ice_ptp_prepare_for_reset().
