dma_addr_t may be either u32 or u64, depending on the kernel configuration,
and we get a warning for the 32-bit case:

drivers/scsi/lpfc/lpfc_nvme.c: In function 'lpfc_nvme_ls_req':
drivers/scsi/lpfc/lpfc_logmsg.h:52:52: error: format '%llu' expects argument of type 'long long unsigned int', but argument 11 has type 'dma_addr_t {aka unsigned int}' [-Werror=format=]
drivers/scsi/lpfc/lpfc_logmsg.h:52:52: error: format '%llu' expects argument of type 'long long unsigned int', but argument 12 has type 'dma_addr_t {aka unsigned int}' [-Werror=format=]
drivers/scsi/lpfc/lpfc_nvme.c: In function 'lpfc_nvme_ls_abort':
drivers/scsi/lpfc/lpfc_logmsg.h:52:52: error: format '%llu' expects argument of type 'long long unsigned int', but argument 11 has type 'dma_addr_t {aka unsigned int}' [-Werror=format=]
drivers/scsi/lpfc/lpfc_logmsg.h:52:52: error: format '%llu' expects argument of type 'long long unsigned int', but argument 12 has type 'dma_addr_t {aka unsigned int}' [-Werror=format=]

printk has a special "%pad" format string that passes the dma address by
reference to solve this problem.
