netdev-tc-offloads: Use correct hook qdisc at init tc flow

A preliminary netdev qdisc cleanup is done during init tc flow.
The cited commit allows for creating of egress hook qdiscs on internal
ports. This breaks the netdev qdisc cleanup as currently only ingress
hook qdiscs type is deleted. As a consequence the check for tc ingress
shared block support fails when the check is done on internal port.

Issue can be reproduced by the following steps:
- start openvswitch service
- create ovs bridge
- restart openvswitch service

Fix by using the correct hook qdisc type at netdev hook qdisc cleanup.
