Subject: [PATCH 39/71] Content server: Fix OPDS feed for category based
 browsing listing restricted books, even though these books cannot be actually
 downloaded.  Fixes #1839173 [opds feed shows other books with same tags when
 those books are not
 allowed.](https://bugs.launchpad.net/calibre/+bug/1839173)
