[PATCH] btree: Export btree_get_prev() so modules can use btree_for_each

From: Roland Dreier

From: Steve Hodgson <steve@xxxxxxxxxxxxxxx>

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.
