Added missing EHB (Execution Hazard Barrier) in mtc0 -> mfc0 sequence. Without this execution hazard barrier it's possible for the value read back from the KScratch register to be the value from before the mtc0.

Reproduciable on P5600 & P6600.

Mips documentation Volume III (rev 6.03) table 8.1.

Applied to mips-fixes.
