Subject: [PATCH] scsi: megaraid_sas: Do not limit queue_depth to 1k in
 non-RDPQ mode
References: bsc#1066909,FATE#322937
Git-commit: 2dba66bf8ecb2dd07b721465c25f537acff6eaf1
Patch-Mainline: v4.15-rc1

Driver load fails if memory allocation for request frame pool fails due
to the higher queue_depth requirement. The driver now allows dynamically
reducing queue_depth if memory allocations fail rather than failing
load.  With this, there is no need to limit queue_depth to 1K.
