In the h != g && shmaddr == NULL && !reserved_va case, target_shmat() incorrectly mmap()s the initial anonymous range with MAP_FIXED_NOREPLACE, even though the earlier mmap_find_vma() has already reserved the respective address range.Fix by using MAP_FIXED when "mapped", which is set after mmap_find_vma(), is true.
