libata: implement and use ATA_QCFLAG_QUIET
Implement ATA_QCFLAG_QUIET which indicates that there's no need to report if the command fails with AC_ERR_DEV and set it for passthrough commands. Combined with previous changes, this now makes device errors for all direct commands reported directly to the issuer without going through EH actions and reporting. Note that EH is still invoked after non-IO device errors to determine the nature of the error and resume command execution (some controller requires special care after error to continue). It just performs default maintenance after error, examines what's going on, realizes that it's none of its business and reports the command failure without logging any error messages.
