fuse: update stats for pages in dropped aux writeback list
commit f7790d67785302b3116bbbfda62a5a44524601a3 upstream.
In the case where the aux writeback list is dropped (e.g. the pages
have been truncated or the connection is broken), the stats for
its pages and backing device info need to be updated as well.
