The filesystem storage driver uses different paths depending on sstable state. It's possible to keep only table directory _and_ state on it and construct this path on demand when needed, but it's faster to keep full path onboard. All the more so it's only exported outside via .prefix() call which is for logs only, but still Signed-off-by: Pavel Emelyanov <xemul@scylladb.com>
