netlink: Unset cb_running when terminating dump on release 

When we terminated the dump, the callback isn't running, so cb_running
should be set to false to be logically consistent.

cb_running signifies whether a dump is ongoing. It is set to true in
cb->start(), and is checked in netlink_dump() to be true initially.
After the dump, it is set to false in the same function.

This is just a cleanup, no path should access this field on a closed
socket.
