i965/fs: Set first_non_payload_grf in assign_curb_setup

first_non_payload_grf may be updated in assign_urb_setup for FS or
assign_vs_urb_setup for VS.

We need to set this in assign_curb_setup for compute shaders since cs
does not have an assign_cs_urb_setup like assign_urb_setup (fs) or
assign_vs_urb_setup (vs).
