bcachefs: Fix a use after free

This fixes a regression from "bcachefs: Stash a copy of key being
overwritten in btree_insert_entry". In btree_key_can_insert_cached(), we
may reallocate the key cache key, invalidating pointers previously
returned by peek() - fix it by issuing a transaction restart.
