Someone with some more mmap-fu, please review.
How about:
if (mm->mm == NULL && !mm->size)
 rv = APR_SUCCESS;
else
 rv = munmap(mm->mm, mm->size);
(My brain isn't awake enough to get the reverse conditional right.)
If a platform gives us address 0 for a non-zero size, well, that's not our 
fault if it complains on munmap.  =)  -- justin
