ni-utils: remove unused wl12xx workaround

The wl12xx WiFi driver is not enabled in our x86_64 configurations. Additionally it is a workaround introduced for AB#735824 and was never revisited in AB#779061. On top of it the assumptions underlying the workaround - that RCU callbacks are processed in softirqs - no longer apply. Remove this dead code. Signed-off-by: Gratian Crisan <[email protected]>
