* ext[23]_xattr_list():

  - Before inserting an xattr block into the cache, make sure that the
    block is not corrupted.  The check got moved after inserting into the
    cache in the xattr consolidation patches, so corrupted blocks could become
    visible to cache users.

  - Take a variable out of the loop that calls the ->list handlers.

* A few cosmetic changes.
