Currently xfs_ino_t is defined as a u64 which can either be an unsigned long long or on some 64 bit platforms and unsigned long. Just making it and unsigned long long mean's it's still always 64 bits wide, but we don't need to resort to cases to print it. Fixes a warning regression on 64 bit powerpc in current git.
