lightnvm: remove dma alloc/free helpers

This patch applies on top of Igor's lightnvm: Flexible metadata (V3). I
took the liberty to rename the new nvm_alloc_dma_pool() to
nvm_create_dma_pool() as it is what is does. Igor, feel free to squash
this part in your patchset. You can also carry this patch on your series
if you want, when you send the V4 to make it easier to Matias to track.

Thanks,
Javier
