Ratelimit and improve formatting.
v2:
- Use a single ratelimit state as suggested by Joe Perches, except I chose to move it up to dmar_fault() so that it includes the "handling fault status reg" pr_err and we can avoid collecting entries for logging if we don't plan to print them. - Added reformatting changes suggested by Joe Perches. - While there is clearly more that could be done with disabling fault handling for specific context entries on storm and sending errors to drivers, this makes a marked improvement on its own.
Thanks, Alex
