[BUG] illegal access error in mixed_join after ODR cleanup PR

[abellina]

This PR (merged to 24.10) inadvertently introduced a bug where a template param (has_nulls) is no longer being passed through, and instead we are hardcoding a value. This is yielding illegal access errors since, I believe we claim the column has a validity mask but it doesn't really.

#16603
