Dave Jiang 4f24543828 dmaengine: idxd: set DMA channel to be private
[ Upstream commit c06e424be5f5184468c5f761c0d2cf1ed0a4e0fc ]

Add DMA_PRIVATE attribute flag to idxd DMA channels. The dedicated WQs are
expected to be used by a single client and not shared. While doing NTB
testing this mistake was discovered, which prevented ntb_transport from
requesting DSA wqs as DMA channels via dma_request_channel().
