ravb: ravb_close() always returns 0
ravb_close() always returns 0, hence the check in ravb_wol_restore() is
pointless (however, we cannot change the prototype of ravb_close() as it
implements the driver's ndo_stop() method).
Found by Linux Verification Center (linuxtesting.org) with the SVACE static
analysis tool.
