Merge branch 'ne/alloc-free-and-null'

The clear_alloc_state() API function was not fully clearing the
structure for reuse, but since nobody reuses it, replace it with a
variant that frees the structure as well, making the callers simpler.

* ne/alloc-free-and-null:
  alloc: fix dangling pointer in alloc_state cleanup
