Some sensor hubs require a get feature report call to be issued soon after changing the power state of the sensor. Without this, the sensor remains in the current state. This patch adds a call soon after the power state. This is retained as a generic call across all sensor hubs since the behavior has been noticed on more than one implementation.

As this isn't a regression (never worked) I've applied it to the togreg branch of iio.git. Thanks, Jonathan
