ata: pata_pxa: Fix DMA channel leak on probe error
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.
