[Mesa-stable] [PATCH 1/2] nvc0/ir: fix wrong emission of (a OP b) OP c

[Samuel Pitoiset]

The third source must be emitted at offset 49 instead of 17 and the
not modifier is at 52 instead of 20. If you look a bit above in
emitLogicOp() you will see that the dest is emitted at 17 which
confirms that src(2) is obviously wrong.
