lightnvm: pass dma address to hardware rather than pointer
A recent change to lightnvm added code to pass a kernel pointer
to the hardware, which gcc complained about:
drivers/nvme/host/lightnvm.c: In function 'nvme_nvm_rqtocmd':
drivers/nvme/host/lightnvm.c:472:32: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
c->ph_rw.metadata = cpu_to_le64(rqd->meta_list);
It looks like this has no way of working anyway, so this changes
the code to pass the dma_address instead. This was most likely
what was intended here. Neither of the two are currently ever
written to, so the effect is the same for now.
