performance/quick-read: disable reading from cache if unlink has
happened after fd was opened.
If dentry being unlinked is the last one, there is a possibility that
later, a new entry with same name being created. After creation of new
file, we shouldn't be returning the contents of this new file, when
application reads using fd opened before unlink.
