dnode_sync is careless with range tree
Because dnode_sync_free_range() must drop dn_mtx during its processing,
using it as a callback to range_tree_vacate() is not safe.  No other
operations (besides destroy) are allowed once range_tree_vacate() has
begun, and dropping dn_mtx would leave a window open for another thread
to observe that invalid (and unsafe) state via dnode_block_freed().
