[issue9990] PyMemoryView_FromObject alters the Py_buffer after calling PyObject_GetBuffer when ndim 1

Here is a patch that fixes the issue. Can you try it?

Unfortunately, more advanced uses such a slicing the memoryview are still crashing. That's because the new buffer protocol doesn't define ownership of Py_buffer structs. As a result, nothing can be assumed at to which piece of code is responsible for allocation and deallocation of related memory areas (such as shapes and strides arrays).
