The recent change (commit 08422d2c559d: "ALSA: memalloc: Allow NULL
device for SNDRV_DMA_TYPE_CONTINOUS type") made the PCM preallocation
helper accepting NULL as the device pointer for the default usage.
Drop the snd_dma_continuous_data() usage that became superfluous from
the callers.

Note that the prerequisite commit 08422d2c559d is found currently only
on for-next branch of sound git tree, so please give ACK if it's OK,
so that I can apply on top of it. Thanks!
