Subject: [PATCH] [PATCH] libata: dec scmd->retries for qcs with zero err_mask

qcs might get retried because of unrelated failure.  e.g. NCQ command
failure causes the whole command set to be aborted.  Decrement
scmd->retries for such retrials to avoid unnecessarily failing
commands.  Note that scmd->retries will be incremented the first time.
