Btrfs: make sure to copy everything if we rename
If we rename a file that is already in the log and we fsync again we will lose the new name. This is because we just log the inode update and not the new ref. To fix this we just need to check if we are logging the new name of the inode and copy all the metadata instead of just updating the inode itself. With this patch my testcase now passes.
