====================
net/sched: fix action batch failure cleanup

Failed batched RTM_NEWACTION requests can leak action references and
reserved IDR indices when cleanup encounters 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 tc-tests/actions/gact-rollback.json

not ok 1 e3b1 - Failed action batch releases a bound action reference
	Could not match regex pattern. Verify command output:
[...]
	 index 1 ref 3 bind 1

not ok 2 e3b2 - Failed action batch releases entries after a bound action
	Command exited with 255, expected 0
RTNETLINK answers: Resource temporarily unavailable
We have an error talking to the kernel

not ok 3 e3b3 - Failed action batch releases repeated references to a bound action
	Could not match regex pattern. Verify command output:
[...]
	 index 1 ref 4 bind 1
