test: : do not increase ref when creating intrusive_ptr<CephContext>
Browse files Browse the repository at this point in the history 
before this change, we increment the refcount when constructing
`cct` instrusive_ptr, but nobody owns this smart pointer. also,
`CephContext` 's constructor set its refcount to 1. so, when the
test finishes, the refcount is 1, and this leads to a leakage of
the `CephContext` instance. and LeakSanitizer points this out:
```
Indirect leak of 10880000 byte(s) in 1 object(s) allocated from:

```

so, in this change, we do not increase the refcount when creating cct.
