Storage controllers are initialized during init and are never modified. NonnullRefPtr can be safely used instead of the NonnullLockRefPtr. This also fixes one of the UB issue that was there when using an NVMe device because of NonnullLockRefPtr. We can add proper locking when we need to modify the storage controllers after init.
