scsi: megaraid_sas: silence a warning
Add a flag to DMA memory allocation to silence a warning. This driver allocates DMA memory for IO frames. This allocation may exceed MAX_ORDER pages for few megaraid_sas controllers (controllers with very high queue depth). Consequently, the driver has logic to keep reducing the controller queue depth until the DMA memory allocation succeeds. On impacted megaraid_sas controllers there would be multiple DMA allocation failures until driver settled on an allocation that fit. These failed DMA allocation requests caused stack traces in system logs. These were not harmful and this patch silences those warnings/stack traces.
