Subject: [PATCH] truncate: don't leak a file descriptor with --ref=PIPE

* src/truncate.c (main): For a user who makes the mistake of
using a non-seekable file as a reference for the desired length,
truncate would open that file, attempt to seek to its end, but
upon seek failure would neglect to close the file descriptor.
Reverse conjuncts, so the close is unconditional.
Spotted by coverity.
