Alexander Motin e11b3eb1c6 ZIL: Do not clone blocks from the future
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().
