Title: DNM: os: FileStore::_touch invalidates the FDCache

It does fix the situation where the primary thinks it has a file where it really does not, because of the cache. But I have no clue if doing this is a valid fix. And it definitely does not solve the more general problem because there still is a window of opportunity for http://tracker.ceph.com/issues/8914 to happen.

What do you think ?
