ALSA: firewire: Convert to the common vmalloc memalloc

Browse Source 
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.
(*) 1fe7f397cf: ALSA: memalloc: Add vmalloc buffer allocation
                  support
    7e8edae39f: ALSA: pcm: Handle special page mapping in the
                  default mmap handler
