pgsql: Fix another buglet in archive_waldump.c.

Fix another buglet in archive_waldump.c.

While re-reading 860359ea0, I noticed another problem: when
spilling to a temp file, it did not bother to check the result
of fclose().  This is bad since write errors (like ENOSPC)
may not be reported until close time.
