    Attachment: HDFS-3045.001.patch

* fsck move should bail on a file if it can't create a block file

Note: This is based on the patch I uploaded for HDFS-3044.  So perhaps it would be best to review/apply that one first.  However, I wanted to put this here before I forgot.

> NamenodeFsck#lostFoundMove, when it fails to create a file for a block continues on to the next block (There's a comment "perhaps we should bail out here..." but it doesn't). It should instead fail the move for that particular file (unwind the directory creation and not delete the original file). Otherwise a transient failure speaking to the NN means this block is lost forever.
