[ Upstream commit 0531b0357ba37464e5c0033e1b7c69bbf5ecd8fb ]
Flower tests used to create ingress filter with specified parent qdisc
"parent ffff:" but dump them on "ingress". With recent commit that fixed
tcm_parent handling in dump those are not considered same parent anymore,
which causes iproute2 tc to emit additional "parent ffff:" in first line of
filter dump output. The change in output causes filter match in tests to
fail.
Prevent parent qdisc output when dumping filters in flower tests by always
correctly specifying "ingress" parent both when creating and dumping
filters.

[ Upstream commit b8215dce7dfd817ca38807f55165bf502146cd68 ]
test_flow_dissector leaves a TAP device after it's finished, potentially
interfering with other tests that will run after it. Fix it by closing the
TAP descriptor on cleanup.
