Subject: [PATCH] block: don't set bounce limit in blk_init_allocated_queue
Git-commit: 0bf6595ec81d896451f0066c95f8cd34c74313dc
Patch-mainline: v4.13-rc1
References: fate#322738,fate#322919,fate#322950,fate#323773
And just move it into scsi_transport_sas which needs it due to low-level
drivers directly derferencing bio_data, and into blk_init_queue_node,
which will need a further push into the callers.
