NVMe: Fix DMA mapping for admin commands
We were always mapping as DMA_FROM_DEVICE then unmapping with DMA_TO_DEVICE which was clearly not correct. Follow the same pattern as nvme_submit_io() and key off the bottom bit of the opcode to determine whether this is a read or a write. Signed-off-by: Matthew Wilcox <matthew.r.wilcox@intel.com>
