fts: avoid crash when a cycle is added while traversing

This could be triggered by auto-mounting a recursive bind mount.
Reported by Michael Chapman in: https://bugzilla.redhat.com/1188498
* lib/fts.c (fts_read): Avoid removing the original hash table item
when leaving a directory that caused a cycle, and preserve the FTS_DC
flag.
