We should use printf format specifier "%u" instead of "%d" for
argument of type "unsigned int".
In addition, fix two error format problems found by checkpatch.pl:
ERROR: space required after that ',' (ctx:VxV)
+        fprintf(stderr,"%s attributes=0x%02x begin=%u size=%d\n",
                       ^
ERROR: line over 90 characters
+        fprintf(stderr, "%d, %s (%u, %d)\n", i, commit->path ? commit->path : "(null)", commit->param.rename.cluster, commit->action);
