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.
