dawn_wire: Skip device inject error if the client drops the device

If the client drops the last reference to the device, it would
dereference an invalid pointer upon calling InjectError. So, skip the
call. We can't keep the device alive if the Buffer is still alive
because we intend to make all objects internally null if you delete
their device.

It is ok to skip error injection because if the client deletes the
device, it should not expect to receive any more error callbacks.
