[sheepdog] [PATCH stable-0.7] zookeeper: fix build failure in sheep/cluster/zookeeper.c

[Ryusuke Konishi]

The commit 8b4a72f310f0e8a14d99187fc97066e1017759b3 "lib: rename
wrappers of pthread_rwlock" mistakenly inserted rb_destroy() in
zk_tree_destroy() function and broke build of zookeeper.

This fixes the issue.
