netlink: fix leaked instances of struct nl_socket
Valgrind detected memory leaks caused by missing cleanup of netlink
context's ethnl_socket, ethnl2_socket and rtnl_socket. Also, contrary to
its description, nlsock_done() does not free struct nl_socket itself.
Fix nlsock_done() to free the structure and use it to dispose of sockets
pointed to by struct nl_context members.
Fixes: 50efb3cdd2bb ("netlink: netlink socket wrapper and helpers")
Fixes: 87307c30724d ("netlink: initialize ethtool netlink socket")
Fixes: 7f3585b22a4b ("netlink: add handler for permaddr (-P)")
