target/xtensa: Explicitly set 2-NaN propagation rule
Set the NaN propagation rule explicitly in xtensa_use_first_nan().
(When we convert the softfloat pickNaNMulAdd routine to also
select a NaN propagation rule at runtime, we will be able to
remove the use_first_nan flag because the propagation rules
will handle everything.)
