CIFS: FS-Cache: Uncache unread pages in cifs_readpages() before freeing them
In cifs_readpages(), we may decide we don't want to read a page after all -
but the page may already have passed through fscache_read_or_alloc_pages() and
thus have marks and reservations set. Thus we have to call
fscache_readpages_cancel() or fscache_uncache_page() on the pages we're
returning to clear the marks.
NFS, AFS and 9P should be unaffected by this as they call read_cache_pages()
which does the cleanup for you.
