iwlwifi: dvm: run INIT firmware again upon .start()
The assumption before this patch was that we don't need to run again the INIT firmware after the system booted. The INIT firmware runs calibrations which impact the physical layer's behavior. Users reported that it may be helpful to run these calibrations again every time the interface is brought up. The penatly is minimal, since the calibrations run fast.
