aco: always use rtne for fquantize2f16

The SPIR-V spec says:

If Value is positive with a magnitude too large to represent as a
16-bit floating-point value, the result is positive infinity.
If Value is negative with a magnitude too large to represent as a
16-bit floating-point value, the result is negative infinity.

This is only the case for rtne v_cvt_f16_f32
