Currently lightnvm and pblk uses single DMA pool, for which the entry size always is equal to PAGE_SIZE. The contents of each entry allocated from the DMA pool consists of a PPA list (8bytes * 64), leaving 56bytes * 64 space for metadata. Since the metadata field can be bigger, such as 128 bytes, the static size does not cover this use-case. This patch adds support for I/O metadata above 56 bytes by changing DMA pool size based on device meta size and allows pblk to use OOB metadata >=16B.
