Curves: Use early out when apapting domain of single value 

When adapting the domain of a single value virtual array, skip
allocating an array for the result and just return another single
value. Among other cases, this can help when everything is selected
in sculpt mode, moving domain interpolation from 5% of perf samples
to 0% when sculpting.
