Subject: [PATCH] scsi: bfa: don't reset max_segments for every bsg request
Git-commit: b8d897ab663f499774bb250db9880139a3b0a229
Patch-mainline: v4.15-rc1
References: bsc#1104967,FATE#325924
We already support 256 or more segments as long as the architecture
supports SG chaining (all the ones that matter do), so removed the weird
playing with limits from the job handler.
