%zu is not always synonymous with uint64_t; on 32-bit machines,
size_t is only 32 bits. Prefer "%lld"/'unsigned long long' when
the variable is under our control, and "%"PRIu64 when we are
stuck with 'uint64_t' from RBD.
Fixes errors such as:
../../src/storage/storage_backend_rbd.c: In function 'virStorageBackendRBDVolWipe':
../../src/storage/storage_backend_rbd.c:1281:15: error: format '%zu' expects argument of type 'size_t', but argument 8 has type 'uint64_t {aka long long unsigned int}' [-Werror=format=]
