rt73usb and rt2500usb used in_atomic to determine if a configuration step should be rescheduled or not. Since in_atomic() is not a valid method to determine if sleeping is allowed we should fix the way this is handled by adding a new flag to rt2x00. In addition mark LED class support for the drivers broken since that also uses the broken in_atomic() method but so far no solution exists to have LED triggers work only in scheduled context.
