Use the correct printf formats, so that a 32-bit compile doesn't
spit out lots of warnings about %lx being incompatible with uint64_t.
Broken since initial commit ef6d4ccd.

I don't know if 'make vm-build-ubuntu.i368' would catch this (it failed
for me for other reasons); I found it via a 32-bit rawhide VM.

That fixes most of the warnings, but not:

/home/dummy/qemu/hw/rdma/rdma_backend.c: In function 'rdma_backend_create_mr': /home/dummy/qemu/hw/rdma/rdma_backend.c:409:37: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
     m4->ibmr = ibv_reg_m4(pd->ibpd, (void *)addr, length, access);
