ALSA: vx: Convert to the common vmalloc memalloc
The recent change (*) in the ALSA memalloc core allows us to drop the special vmalloc-specific allocation and page handling. This patch coverts to the common code. (*) 1fe7f397cfe2: ALSA: memalloc: Add vmalloc buffer allocation support 7e8edae39fd1: ALSA: pcm: Handle special page mapping in the default mmap handler Since the driver requires the DMA32 allocation, it passes the specially encoded device to snd_pcm_lib_preallocate_pages().
