Uhm. I think Dovecot's code should rather be fixed so the function
doesn't get called with closed file descriptors. I'm not sure if it's
possible everywhere without larger changes though..

Anyway I don't think you should add the extra fstat() there, not giving
a warning if EBADF error comes is just as good without extra syscall.
