Description
Removes extra range proof verifications that are done if batch verification fails.
Motivation and Context
If a batch of range proofs fails verification, each proof is checked separately until an invalid proof is found; this is reported for debugging purposes, but is otherwise not used.
This is inefficient and can lead to denial of service.
Until (or unless) #6167 is implemented to provide a more efficient method of identifying an invalid proof, this PR removes the unused extra verification operations.
How Has This Been Tested?
Existing tests pass.
What process can a PR reviewer use to test or verify this change?
Confirm that the existing verification operations were unused (except for debugging purposes), and that batch verification continues to work as expected.
