Btrfs: release both paths before logging dir/changed extents
The ceph guys tripped over this bug where we were still holding onto the original path that we used to copy the inode with when logging. This is based on Chris's fix which was reported to fix the problem. We need to drop the paths in two cases anyway so just move the drop up so that we don't have duplicate code.
