### Rationale for this change The null count is not updated when setting slice on an array span, after a preceding set slice sees a 0 null count. An incorrectly null count will cause subsequent failures wrt. null processing like #47807. ### What changes are included in this PR? Narrowing the null count update condition when setting slice on an array span: as long as there is a valid buffer, we set null count to unknown. ### Are these changes tested? Test included. ### Are there any user-facing changes? None. -- This is an automated message from the Apache Git Service.
