The rfkill state Sysfs attribute should be made writable,
we already pass the argument for the store handler,
so we only need to update the permissions flag.

Subject: [patch] net/input: fix net/rfkill/rfkill-input.c bug on 64-bit systems

     [NET]: rfkill: add support for input key to control wireless radio

added this 64-bit bug:

        ....
	unsigned int flags;
 
 	spin_lock_irqsave(&task->lock, flags);
        ....

irq 'flags' must be unsigned long, not unsigned int. The -rt tree has 
strict checks about this on 64-bit so this triggered a build failure.
