Fix bad-free in psync_interval_tree_free 

Interval tree nodes are allocated via pmem_malloc, which prepends a
16-byte header. Passing bare free() to ptree_for_each_element_call_safe
freed the wrong address. Add free_interval_tree_node() helper that uses
pmem_free and use it in psync_interval_tree_free.
