[PATCH net v1 2/2] selftests: tc-testing: test action batch deletion failure cleanup

[Xuanqiang Luo]

From: Xuanqiang Luo <luoxuanqiang@xxxxxxxxxx>

Add tests for cleanup after a batched RTM_DELACTION request fails at
a gact action bound to a filter. Check that subsequent actions retain
their original reference counts and that earlier successful deletions
are preserved.

Cover failures at the first and middle entries. Verify that a remaining
unbound action can be removed with one subsequent delete.
