zhangshoukui f57a5a6802 fs/vfs/fs_dup.c: before file_allocate should restore minfd if define FDCHECK 
When we use fcntl for dup, an fd is directly passed. If we have opened FDCHECK. we need to restore this file descriptor.

open FDCHECK and test this：

`
int main(int ac, char **av)
{
  int fd1= open("./1.txt", O_WRONLY | O_CREAT, 0666);
  if (fd1 < 0)
    {
      printf("open err\n");
      return fd1;
  }

  int fd2= open("./2.txt", O_WRONLY | O_CREAT, 0666);
  if (fd2 < 0)
    {
      printf("open err\n");
      close(fd1);
      return fd2;
    }

  //close(fd2);
  int fd3 = fcntl(fd1, F_DUPFD, fd2);
  printf("fd3 = %d\n", fd3);
  close(fd1);
  close(fd3);
  return 0;
}
`
