ZIL: Replay blocks without next block pointer.

Browse Source 
If we get next block allocation error during log write, we trigger
transaction commit.  But the block we have just completed is still
written and transactions it covers will be acknowledged normally.
If after that we ignore the block during replay just because it is
the last in the chain, we may not replay some transactions that we
have acknowledged as synced, that is not right.
