ATA devices (struct ata_device) have a max_sectors field which is

associated sdev request queue max_sectors value from how it is earlier set
in __scsi_init_queue(). In __scsi_init_queue() the max_sectors value is set
according to shost limits, which includes host DMA mapping limits.
Cap the ata_device max_sectors according to shost->max_sectors to respect
this shost limit.

Nit: please change the patch title to "ata: libata-scsi: Cap ..."
ok, but it's going to be an even longer title :)
BTW, this patch has no real dependency on the rest of the series, so
could be taken separately if you prefer.
Thanks,
John
