Use ata_wait_after_reset() to poll for link recovery after a reset. This combined with sas_ha->eh_mutex prevents expander rediscovery from probing phys in an intermediate state. Local discovery does not have a mechanism to filter link status changes during this timeout, so it remains the responsibility of lldds to prevent premature port teardown. Although once all lldd's support ->lldd_ata_check_ready() that could be used as a gate to local port teardown. The signature fis is re-transmitted when the link comes back so we should be revalidating the ata device class, but that is left to a future patch.
