Ben Dooks 54aa6c4936 dmaengine: dw-axi-dmac: ignore interrupt if no descriptor ...

[ Upstream commit 820f5ce999d2f99961e88c16d65cd26764df0590 ]

If the channel has no descriptor and the interrupt is raised then the
kernel will OOPS. Check the result of vchan_next_desc() in the handler
axi_chan_block_xfer_complete() to avoid the error happening.
