dell-laptop: Block software state changes when rfkill hard blocked
The "hardware" switch is tied directly to a BIOS interface that will connect and disconnect the hardware from the bus. If you use the software interface to request the BIOS to make these changes, the HW switch will be in an inconsistent state and LEDs may not reflect the state of the HW.
