MIPS: DEC: Rate-limit memory errors for KN01 systems

Similarly to memory errors in ECC systems also rate-limit memory parity
errors for KN01 DECstation and DECsystem models.  Unlike with ECC these
events are always fatal and are less likely to cause a message flood,
but handle them the same way for consistency.
