813aabb04a Fix CPU::StreamState extraScanlinesAfterNmi argument 
Previously the CPU::StreamState function passed the
extraScanlinesBeforeNmi value twice to Stream().

Change the second argument to extraScanlinesAfterNmi instead.

f7ff089689 Core: Fix NMI code to better reflect the hardware 
Fixes a crash in Super Chinese 3 caused by the PPU rapidly switching the NMI signal on and then back off (which caused the CPU to incorrectly jump to the IRQ handler and crashed the game)
