btrfs: add btrfs_tree_block_status definitions to tree-checker.h 



We use this in btrfs-progs to determine if we can fix different types of
corruptions.  We don't care about this in the kernel, however it would
be good to share this code between the kernel and btrfs-progs, so add
the status definitions so we can start converting the tree-checker code
over to using these status flags instead of blanket returning -EUCLEAN.
