i965/vec4: fix assert to detect SIMD lowered DF instructions in IVB
On IVB, DF instructions have lowered the SIMD width to 4 but the
exec_size will be later doubled. Fix the assert to avoid crashing in
this case.

[ Francisco Jerez: Simplify assert. Except for the 'inst->group % 4
== 0' part the assertion was redundant with the previous assertion. ]
