spi: atcspi200: Fix double-free in atcspi_configure_dma()
The driver uses devm_dma_request_chan() which registers automatic cleanup
via devm_add_action_or_reset(). Calling dma_release_channel() manually on
the RX channel when TX channel request fails causes a double-free when
the devm cleanup runs.
Remove the unnecessary manual cleanup and simplify the error handling
since devm will properly release channels on probe failure or driver
detach.
