fuse: decrement NR_WRITEBACK_TEMP on the right page
commit a2ebba824106dabe79937a9f29a875f837e1b6d4 upstream.
NR_WRITEBACK_TEMP is accounted on the temporary page in the request, not
the page cache page.
Fixes: 8b284dc47291 ("fuse: writepages: handle same page rewrites")
Cc: <stable@vger.kernel.org> # v3.13
