selftests/bpf, flow_dissector: Close TAP device FD after the test
[ 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.
