aa8877d5c1 act: remove rtnl_act_alloc_cache()
It is complicated to cache tc actions, they are different
from tc qdisc's and filters by design. So, it is simple
if we just don't cache them.

This patch only removes the tc action cache allocation API.
We still need to bypass the libnl cache layer from scratch,
but that would not break ABI any more, therefore we can do
it later.

2cf635b06a route: add libnl name prefix to global variable link_policy

Introduced by commit 8026fe2e3a ("link:
Free and realloc af specific data upon rtnl_link_set_family()")

link->l_af_data[link->l_af_ops->ao_family] is freed here but not set to
zero. That leads to double free made by link_free_data->do_foreach_af.

Fix this by setting link->l_af_data[link->l_af_ops->ao_family] to zero
rigth after free.

ded20487fd link: Fix rtnl_link_af_data_compare return value
This patch fixes a bug where because of the af_ops check
being first in the function, we were returning ~0 if af_ops
was null even if both objects really did not have af_data
and we should be returning 0.

Its better to have the af_data present check before anything else.

So, Rearranged some of the code in rtnl_link_af_data_compare.
Changes include:
	- Do the attribute present check before anything else
	- If ao_compare op not present, return ~0
