ASoC: Fix pxa2xx-pcm checks for invalid DMA channels
Set the invalid dma channel to -1 (and check properly for it) in pxa2xx_pcm_hw_free(). Was assuming 0 is an invalid channel number but 0 is a valid pxa dma channel num. Signed-off-by: stephen <stephen.ware@eqware.net> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
