Pull two btrfs reverts from Chris Mason:
 "I had missed that for two of the patches in my last pull, we had
  included different fixes during 3.7."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs:
  Revert "Btrfs: reorder tree mod log operations in deleting a pointer"
  Revert "Btrfs: MOD_LOG_KEY_REMOVE_WHILE_MOVING never change node's nritems"
