partitions: don't allocate dma capable memory
While block drivers may do DMA, they always use block caching chunks as
bounce buffer. No dma is every done directly to the block_read data
argument, so it doesn't need to be allocated with dma_alloc. The buffer
also need not be zeroed, as block_read will either overwrite it
completely or fail.
