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.
