ceph: fix race during filling readdir cache
commit af5e5eb574776cdf1b756a27cc437bff257e22fe upstream.
Readdir cache uses page cache to save dentry pointers. When adding
dentry pointers to middle of a page, we need to make sure the page
already exists. Otherwise the beginning part of the page will be
invalid pointers.
