Guennadi Liakhovetski 7c1119bdd6 dma: sh: Don't use ENODEV for failing slave lookup ...

If dmaengine driver's .device_alloc_chan_resources() method returns -ENODEV,
dma_request_channel() will decide, that the driver has been removed and will
remove the device from its list. To prevent this use ENXIO if a slave lookup
fails.
