msm: camera: sensor: Do not use interruptible wait call in CCI

If we terminate (-ERESTARTSYS signal) before sending last
i2c message with a stop condition, the bus remains busy
and we are not able to send new messages into bus with
successive CCI calls. Therefore a pending signal is not
caught here and we return only because of timeout or
i2c error.
