Fixed a race contidion in StorageManagerService

StorageManagerService#onVolumeStateChanged passes on a mutable
object to onVolumeStateChangedLocked and onVolumeStateChangedAsync.
This causes a race since the state of the object being passed can
be updated while onVolumeStateChangedAsync is processing it.

To fix this, a clone of the object is passed instead.
