Subject: [PATCH] ASoC: Intel: Skylake: Convert buffer size to # of u32
 elements before allocating memory

While allocating memory, kfifo expects the number of elements in arguments
and not the # of bytes. Due to this, kfifo is currently allocating 4 times
the memory requested by user. Convert buffer size to the number of elements
before allocating memory.
