dm btree: fix leak of bufio-backed block in btree_split_beneath error path
[ Upstream commit 4dcb8b57df3593dcb20481d9d6cf79d1dc1534be ]
btree_split_beneath()'s error path had an outstanding FIXME that speaks
directly to the potential for _not_ cleaning up a previously allocated
bufio-backed block.
Fix this by releasing the previously allocated bufio block using
unlock_block().
