nvme_dbbuf_dma_free frees dma coherent memory, so it must not be called after ->remove has returned. Fortunately there is no way to use it after shutdown as no more I/O is possible so it can be moved. Similarly the iod_mempool can't be used for a device kept alive after shutdown, so move it next to freeing the PRP pools.
