  Log Message:
  -----------
  ofp-group: Use big-enough buffer in ofputil_format_group().

GCC 11 pointed out that ofputil_group_to_string()'s prototype asks for
a buffer with one byte more than supplied.  This fixes the problem.

This wasn't a buffer overflow because ofputil_group_to_string() honors
the buffer size passed in, which was correct.  The worst that could
happen was truncating the last byte of a group name.
