gh-142884: Fix UAF in `array.array.tofile` with concurrent mutations
the original code precomputed nblocks at the beginning of the function, but when a reentrant writer cleared the array during the first callback, self->ob_item became NULL. The loop continued iterating based on the cached values and dereferenced the null pointer.

Don't rebase upstream/main, just merge main into your branch.
