ZIL claim can not handle block pointers cloned from the future, since they are not yet allocated at that point. It may happen either if the block was just written when it was cloned, or if the pool was frozen or somehow else rewound on import. Handle it from two sides: prevent cloning of blocks with physical birth time from not yet synced or frozen TXG, and abort ZIL claim if we still detect such blocks due to rewind or something else. While there, assert that any cloned blocks we claim are really allocated by calling metaslab_check_free().
