libata: clear ering on resume

Error timestamps are in jiffies which doesn't run while suspended and
PHY events during resume isn't too uncommon.  When the two are
combined, it can lead to unnecessary speed downs if the machine is
suspended and resumed repeatedly.  Clear error history on resume.

This was reported and verified in bnc#486803 by Vladimir Botka.
