async_tx: Fix DMA_PREP_FENCE usage in do_async_gen_syndrome()
The DMA_PREP_FENCE is to be used when preparing Tx descriptor if output
of Tx descriptor is to be used by next/dependent Tx descriptor.
The DMA_PREP_FENSE will not be set correctly in do_async_gen_syndrome()
when calling dma->device_prep_dma_pq() under following conditions:
1. ASYNC_TX_FENCE not set in submit->flags
2. DMA_PREP_FENCE not set in dma_flags
3. src_cnt (= (disks - 2)) is greater than dma_maxpq(dma, dma_flags)
This patch fixes DMA_PREP_FENCE usage in do_async_gen_syndrome() taking
inspiration from do_async_xor() implementation.
