Josef Bacik b8399dee47 Btrfs: do not do fast caching if we are allocating blocks for tree_root ...

Since the fast caching uses normal tree locking, we can possibly deadlock if we
get to the caching via a btrfs_search_slot() on the tree_root.  So just check to
see if the root we are on is the tree root, and just don't do the fast caching.
