Btrfs: clear pages dirty for io and set them extent mapped
When doing the io_ctl helpers to clean up the free space cache stuff I stopped using our normal prepare_pages stuff, which means I of course forgot to do things like set the pages extent mapped, which will cause us all sorts of wonderful propblems. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com>
