ata: libata: ata_{sff|std}_prereset() always return 0
ata_std_prereset() always returns 0, hence the check in ata_sff_prereset()
is pointless and thus it also can return only 0 (however, we cannot change
the prototypes of ata_{sff|std}_prereset() as they implement the driver's
prereset() method).
Found by Linux Verification Center (linuxtesting.org) with the SVACE static
analysis tool.
