Alexander Aring 17e84a9253 at86rf230: mask irq's before deregister device 
While transmit over a at86rf231 device and unloading the module I got:

The problem is there are still interrupts after deregister ieee802154
device. This patch mask all interrupts in the at86rf2xx chips before
deregister the device.
