[PATCH net v1 0/2] net/sched: fix action batch deletion cleanup

From: Xuanqiang Luo <redacted>

Batched RTM_DELACTION requests can leak references to unprocessed actions
when deletion stops at a filter-bound action.

Patch 1 fixes the failure cleanup.

Patch 2 adds tc-testing regression coverage.

Failure reproduction (key output excerpts):

  python3 tdc.py -f /root/tc-testing/batch-delete.json

not ok 1 d710 - Release tail references after first action deletion fails
	Could not match regex pattern. Verify command output:
[...]
	 index 2 ref 2 bind 0
[...]
	 index 3 ref 2 bind 0

not ok 2 d711 - Release tail references after middle action deletion fails
	Could not match regex pattern. Verify command output:
[...]
	 index 3 ref 2 bind 0

not ok 3 d713 - Delete a tail action once after a failed batch
	Could not match regex pattern. Verify command output:
total acts 2
[...]
	 index 2 ref 1 bind 0
