The hsr_ping test reports the following errors:

That is because the cleanup code for the 2nd round test before "setup_hsr_interfaces 1" is removed incorrectly in commit 680fda4f6714 ("test: hsr: Remove script code already implemented in lib.sh").
This patch fixes it by adding a new helper delete_hsr_interfaces() to delete all interfaces before "setup_hsr_interfaces 1".

nit: you can also just re-setup the namespaces, which will delete previous ns and create new one. e.g.
setup_ns ns1 ns2 ns3
setup_hsr_interfaces 1 do_complete_ping_test
