vlib: pre-alloc dma backend batches
Allocate and initialize dma batch structure when adding dma config. The number of required dma batches is set by max_batches parameter. Thus dma batches are not allocated dynamically in worker thread. Application need to check the return value of vlib_dma_batch_new. Type: improvement Signed-off-by: Marvin Liu <yong.liu@intel.com> Change-Id: I5d05a67b59634cf2862a377d5ab77cb1040343ce
