[SCSI] bfa: DMA memory allocation enhancement.
- Modified the design such that each BFA sub-module will provide
the amount of DMA and KVA memory needed by it and queues the
same request to the global dma and kva info queues.
- During the memory allocation we iterate over this queue to allocate
the dma and kva memory requested by sub-modules.
- The change is needed to avoid requesting the aggregate amount of memory
needed by all the BFA sub-modules as one contiguous chunk.
