The memory the parameter __key points to is used as an iterator in btree_get_prev(), so if we save off a bkey() pointer in retry_key and then assign that to __key, we'll end up corrupting the btree internals when we do eg longcpy(__key, bkey(geo, node, i), geo->keylen); to return the key value. What we should do instead is use longcpy() to copy the key value that retry_key points to __key. This can cause a btree to get corrupted by seemingly read-only operations such as btree_for_each_safe.

The btree_for_each API is implemented with macros that internally call btree_get_prev(), so if btree_get_prev() isn't exported then modules fail to link if they try to use one of the btree_for_each macros. Since the rest of the btree API is exported, we should keep things orthogonal and make this work too.
