The function parameter name was wrong in kdocs.

net/mac802154/util.c:27: warning: Function parameter or member 'hw' not described in 'ieee802154_wake_queue'
net/mac802154/util.c:27: warning: Excess function parameter 'local' description in 'ieee802154_wake_queue'
net/mac802154/util.c:53: warning: Function parameter or member 'hw' not described in 'ieee802154_stop_queue'
net/mac802154/util.c:53: warning: Excess function parameter 'local' description in 'ieee802154_stop_queue'
