[Python] Logging memory pool crashes if set as the default memory pool

This crashes:

```
In [1]: pa.set_memory_pool(pa.logging_memory_pool(pa.default_memory_pool()))

In [2]: pa.array([1, 2, 3])
Segmentation fault (core dumped)
```

while passing it as an argument to the function allocating the data works fine:

```
In [1]: pa.array([1, 2, 3], memory_pool=pa.logging_memory_pool(pa.default_memory_pool()))
Allocate: size = 256, alignment = 64
Allocate: size = 64, alignment = 64
Reallocate: old_size = 256, new_size = 64, alignment = 64
Free: size = 64, alignment = 64
Out[1]:

[
1,
2,
3
]
```
