bdev/null: allocate bdev struct using regular calloc

Browse Source 
spdk_dma_malloc() is not required here, as the bdev
struct is neither DMA-able nor shared between processes.

While here, also allocate g_null_read_buf using
spdk_zmalloc() instead of spdk_dma_zmalloc(),
as spdk_dma_*malloc() is about to be deprecated.
