mv_xor mv_xor.0: DMA-API: device driver frees DMA memory with different
direction [device address=0x000000001dea4000] [size=4096 bytes] [mapped with
DMA_FROM_DEVICE] [unmapped with DMA_BIDIRECTIONAL]
Change xor self test destination buffer allocation direction to bidirectional,
as it's what mv_xor_run_tx_complete_actions() frees for multiple sources.
