4.14-stable review patch. If anyone has any objections, please let me know.

From: Mike Rapoport <rppt@xxxxxxxxxxxxxxxxxx>
commit 6685b357363bfe295e3ae73665014db4aed62c58 upstream.
The commit ca460b3c9627 ("percpu: introduce bitmap metadata blocks")
introduced bitmap metadata blocks. These metadata blocks are allocated
whenever a new chunk is created, but they are never freed. Fix it.
