Peter Ujfalusi a057cc79ba dmaengine: of-dma: Fix of_dma_router_xlate's of_dma_xlate handling 
[ Upstream commit 5b2aa9f918f6837ae943557f8cec02c34fcf80e7 ]

of_dma_xlate callback can return ERR_PTR as well NULL in case of failure.

If error code is returned (not NULL) then the route should be released and
the router should not be registered for the channel.
