wimax/i2400m: fix i2400m->wake_tx_skb handling
i2400m_net_wake_tx() sets ->wake_tx_skb with the given skb if ->wake_tx_ws is not pending; however, i2400m_wake_tx_work() could have just started execution and haven't fetched -><wake_tx_skb yet. The previous packet will be leaked. Update ->wake_tx_skb handling. * i2400m_net_wake_tx() now tests whether the previous ->wake_tx_skb has been consumed by ->wake_tx_ws instead of testing work_pending(). * i2400m_net_wake_stop() is simplified similarly. It always puts ->wake_tx_skb if non-NULL. * Spurious ->wake_tx_skb dereference outside critical section dropped from i2400m_wake_tx_work(). Only compile tested.
