Fix the order of src0_alpha and sample mask in fb payload.
From SKL PRM Volume 7, "Data Payload Register Order
for Render Target Write Messages":
Type S0A oM sZ oS M2 M3 M4
SIMD8 1 1 0 0 s0A oM R
SIMD16 1 1 0 0 1/0s0A 3/2s0A oM
It also fixes working of alpha to coverage with sample mask
on GEN6 since now they are in correct order.
