Silence Coverity warning about unused visibilitymap_clear() result Commit c0d9864f5ce made all but one caller of visibilitymap_clear() check its return value, causing Coverity to flag the remaining unchecked call in heap_page_fix_vm_corruption().
This VM clear is not WAL-logged, so the caller doesn't need the return value of visibilitymap_clear(). Add an explicit void cast and comment to document that the return value is intentionally ignored. Backpatch to 19 when the number of callers discarding the return value dropped low enough to trigger Coverity's warning.
