dm integrity: limit the rate of error messages
When using dm-integrity underneath md-raid, some tests with raid auto-correction trigger large amounts of integrity failures - and all these failures print an error message. These messages can bring the system to a halt if the system is using serial console. Fix this by limiting the rate of error messages - it improves the speed of raid recovery and avoids the hang.
