Andy Shevchenko 0f6a928d03 acpi-dma: convert to return error code when asked for channel 
Currently acpi_dma_request_slave_chan_by_index() and
acpi_dma_request_slave_chan_by_name() return only requested channel or NULL.
This patch converts them to return appropriate error code instead of NULL in
case of unsuccessfull request.
