Josef Bacik 416e3445ef btrfs: remove lockdep classes for the fs tree ... We have this weird problem where our lockdep class is set after we read a tree block, which can race with concurrent readers and result in erroneous lockdep errors. We want to set the lockdep class at allocation time if possible, but in certain cases we may not have the actual root owner, such as with relocation or any backref lookups. This is only really a problem for reference counted trees, because all other trees have their root reference set in their extent reference. Remove the fs tree specific lock class. We need to still keep the reloc tree one, it's still reference counted, because replace_path will lock the reloc tree and the destination tree, and if they're both set to tree-<level> we'll have issues.
