mpoeter 77f4799515 Fix potential leak when reusing PinnableSlice instances. (#10166) ... Summary: `PinnableSlice` may hold a handle to a cache value which must be released to correctly decrement the ref-counter. However, when `PinnableSlice` variables are reused, e.g. like this: ``` PinnableSlice pin_slice; db.Get("foo", &pin_slice); db.Get("foo", &pin_slice); ``` then the second `Get` simply overwrites the old value in `pin_slice` and the handle returned by the first `Get` is _not_ released. This PR adds `Reset` calls to the `Get`/`MultiGet` calls that accept `PinnableSlice` arguments to ensure proper cleanup of old values.
