sas_ata_strategy_handler() adds the works of the ata error handler
to system_unbound_wq. This workqueue asynchronously runs work items,

Are there more than one error handling work items per host?

The ata error handler here means async_sas_ata_eh(), every port will
execute it's own async_sas_ata_eh() in sas_ata_strategy_handler().

Thanks.
