gpu: nvgpu: fix sim readl output configuration

Browse Source 
In nvgpu_sim_esc_readl() we prepare a message, issue RPC and then copy back
the response from offset "data_offset + 0xc"

But while configuring the message we incorrectly set the response offset as
just "data_offset"

Fix this by correctly configuring the response offset as "data_offset + 0xc"
