[Qemu-trivial] [PATCH for-2.12] rdma: Fix 32-bit compilation

[Eric Blake]

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.
