bcachefs: Fix a deadlock

__bch2_btree_node_lock() was incorrectly using iter->pos as a proxy for
btree node lock ordering, this caused an off by one error that was
triggered by bch2_btree_node_get_sibling() getting the previous node.

This refactors the code to compare against btree node keys directly.
