SoftGPU: Don't count a block ending at the stride as reaching the next row

Browse Source 
PendingWriteIn took a block that ends exactly at the stride for one running into the next row.
Ridge Racer keeps its CLUTs in the framebuffer's stride gap (the last 64 bytes of 1024-byte rows,
past the 960 drawn), so every CLUT load flushed all queued drawing. Ridge Racer 8% faster.
