[NFC] Remove redundant CalculateSmallVectorDefaultInlinedElements usage from to_vector utility

[yurai007]

Summary

CalculateSmallVectorDefaultInlinedElements<..>::value is already used as default value for second template parameter in SmallVector class declaration.
There is no need to pass it explicitly in to_vector.
