was granted via rings and ni_bufs_list_head represented in those rings and lists (e.g., via SIGKILL), those buffers are no longer available for subsequent users for the lifetime of the system. To mitigate this resource leak, reset the allocator state when the last ref to that allocator is released. Note that this only recovers leaked resources for an allocator when there are no longer any users of that allocator, so there remain circumstances in which leaked allocator resources may not ever be recovered - consider a set of multiple netmap processes that are all using the same allocator (say, the global allocator) where members of that set may be killed and restarted over time but at any given point there is one member of that set running.
