MLK-9655-1 mm: dma: remove duplicated list_add for dma page_list
Since pool_alloc_page_nonbufferable already do list_add, so
dma_pool_alloc_nonbufferable cannot do it again, which will result
in page_list mess and kernel panic when destory pool of memory block
alloced by dma_pool_alloc_nonbufferable.
This patch also can fix MLK-9656.
