When managing shost->host_eh_scheduled libata assumes that there is a 1:1 shost-to-ata_port relationship. libsas creates a 1:N relationship so it needs to manage host_eh_scheduled cumulatively at the host level. The sched_eh and end_eh port port ops allow libsas to track when domain devices enter/leave the "eh-pending" state under ha->lock (previously named ha->state_lock, but it is no longer just a lock for ha->state changes). Since host_eh_scheduled indicates eh without backing commands pinning the device it can be deallocated at any time. Move the taking of the domain_device reference under the port_lock to guarantee that the ata_port stays around for the duration of eh.
