Subject: Avoid the double-free (first in fts_read, second in fts_close) that
 would occur when an `active' directory is made inaccessible (e.g., via chmod
 a-x) during a traversal.

(fts_read): After a failed fchdir, update sp->fts_cur
before returning.  Reproduce this failure by
mkdir -p a/b; cd a; chmod a-x . b
Reported by Stavros Passas.
