ALSA: 6fire: 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
