Use mutable bitmap unset_bits in primitive array iter()

[urvishdesai]

Hi, I am trying to create a MutablePrimitiveArray from array of type &mut PrimitiveArray using array.iter().

I have set some bits as null after initialization.

Now while creating the mutable array with
mutable = MutablePrimitiveArray::from_trusted_len_iter(array.iter()) => array.iter() which calls
ZipValidity::new_with_validity(self.values().iter(), self.validity()) => new_with_validity() that checks
if (validity.unset_bits()) > 0.

I would like to use MutableBitmap::unset_bits() that calls count_zeros() instead of the immutable one that returns the cached value. What do you suggest I do to get the correct Option validity in the result mutable_array MutablePrimitiveArray?
