btrfs: sink writepage parameter to extent_write_cache_pages
The function extent_write_cache_pages is modelled after write_cache_pages which is a generic interface and the writepage parameter makes sense there. In btrfs we know exactly which callback we're going to use, so we can pass it directly. Signed-off-by: David Sterba <dsterba@suse.com>
