IPoIB: Drop priv->lock before calling ipoib_send()
IPoIB currently must use irqsave locking for priv->lock, since it is taken from interrupt context in one path. However, ipoib_send() does skb_orphan(), and the network stack locking is not IRQ-safe. Therefore we need to make sure we don't hold priv->lock when calling ipoib_send() to avoid lockdep warnings (the code was almost certainly safe in practice, since the only code path that takes priv->lock from interrupt context would never call into the network stack).
