Code for pools before version 11 uses dmu_objset_find_dp() to scan
for children datasets/clones. It calls enqueue_clones_cb() and
enqueue_cb() callbacks in parallel from multiple taskq threads.
It ends up bad for scan_ds_queue_insert(), corrupting scn_queue
AVL-tree. Fix it by introducing a mutex to protect those two
scan_ds_queue_insert() calls. All other calls are done from the
sync thread and so serialized.
