net, cls: also reject deleting all filters when TCA_KIND present

Browse Source 
When we check for RTM_DELTFILTER, we should also reject the request
for deleting all filters under a given parent when TCA_KIND attribute
is present. If present, it's currently just ignored but there's also
no point to let it pass in the first place either since this doesn't
have any meaning with wild-card removal.

Fixes: ea7f8277f9 ("net, cls: allow for deleting all filters for given parent")
