Wentao Liang 566d5bf1e2 ata: pata_pxa: Fix DMA channel leak on probe error 
commit fcaf242e7f upstream.

When dmaengine_slave_config() fails, the DMA channel acquired by
dma_request_chan() is not released before returning the error,
leaking the channel reference.

Fix by adding dma_release_channel() in the error path.

The ata_host_activate() error path already correctly releases the
DMA channel.
