Subject: [PATCH net v1] selftests: iou-zcrx: Clean up build warnings for error format

Clean up two build warnings:

[1]:
iou-zcrx.c: In function ‘process_recvzc’:
iou-zcrx.c:263:37: warning: too many arguments for
  format [-Wformat-extra-args]
  263 |               error(1, 0, "payload mismatch at ", i);
      |                           ^~~~~~~~~~~~~~~~~~~~~~

[2]:
iou-zcrx.c: In function ‘run_client’:
iou-zcrx.c:357:47: warning: format ‘%d’ expects argument of
  type ‘int’, but argument 4 has
  type ‘ssize_t’ {aka ‘long int’} [-Wformat=]
  357 |               error(1, 0, "send(): %d", sent);
      |                                    ~^   ~~~~
      |                                     |   |
      |                                     int ssize_t {aka long int}
      |                                    %ld
