Arnd Bergmann 038d710fca scsi: qla2xxx: avoid printf format warning
Depending on the target architecture and configuration, both phys_addr_t
and dma_addr_t may be smaller than 'long long', so we get a warning when
printing either of them using the %llx format string:

drivers/scsi/qla2xxx/qla_iocb.c: In function 'qla24xx_walk_and_build_prot_sglist':
drivers/scsi/qla2xxx/qla_iocb.c:1140:46: error: format '%llx' expects argument of type 'long long unsigned int', but argument 6 has type 'dma_addr_t' {aka 'unsigned int'} [-Werror=format=]
         "%s: page boundary crossing (phys=%llx len=%x)\n",
                                           ~~~^

         __func__, sle_phys, sg->length);
                   ~~~~~~~~
drivers/scsi/qla2xxx/qla_iocb.c:1180:29: error: format '%llx' expects argument of type 'long long unsigned int', but argument 7 has type 'dma_addr_t' {aka 'unsigned int'} [-Werror=format=]
        "%s: sg[%x] (phys=%llx sglen=%x) ldma_sg_len: %x dif_bundl_len: %x ldma_needed: %x\n",
                          ~~~^

There are special %pad and %pap format strings in Linux that we could use
here, but since the driver already does 64-bit arithmetic on the values,
using a plain 'u64' seems more consistent here.

Note: A possible related issue may be that the driver possibly checks the
wrong kind of overflow: when an IOMMU is in use, buffers that cross a
32-bit boundary in physical addresses would still be mapped into dma
addresses within the low 4GB space, so I suspect that we actually want to
check sg_dma_address() instead of sg_phys() here.
