When a missing device is encountered the registration of the remaining PHYs is stopped and the MDIO bus will fail to register. Propagate all errors except ENODEV to avoid it.

When MDTS is not set, the driver sets the max sectors to UINT_MAX, which is not a power of 2, hitting a BUG_ON from blk_queue_chunk_sectors. This patch skips setting chunk sectors for such devices.
