We just free the log root after we set it up when we open a ctree in the tools. This isn't nice, it makes double free's and leaks eb's, makes segfaults with btrfs-image. So fix this to be correct, and fix the cleanup if the buffer is not uptodate. With this fix I no longer segfault trying to do btrfs-image on a file system with a log tree.
