Fix for attention layers to remain unquantized during moe_wn16 quant (#12570)

Fix to AWQ quant loading of the new R1 model

The new optimized MoE kernels for a large number of experts `moe_wn16`
uses AWQ quant which requires the attention layers to be in 16bit

The current merge has broken this, and the `get_quant_method` must
return None for it to work correctly again
