[PATCH 5/6] libata: request PHY speed configuration on SControl access failure

[Tejun Heo <htejun@gmail.com>]

In sata_set_spd_needed(), if SControl read failed, it returned 0 and
skipped PHY speed configuration.  However, if SControl access fails,
it's far more logical to request PHY speed configuration.  Reverse the
logic.
