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
