* Decide if a (locked) device is ready for use
* Before using the device structure, it must be locked
* (wimax_dev->mutex). As well, most operations need to call this
* function to check if the state is the right one.
* An error value will be returned if the state is not the right
* one. In that case, the caller should not attempt to use the device
* and just unlock it.
