[PATCH] libertas: remove unused variables in wlan_dev_t

Actually, this patch removev wlan_dev_t totally and puts the used variables
of it directly into wlan_private. That reduces one level of indirection and
looks a little bit simpler. It's now "priv->card" and not
"priv->wlan_dev.card" and "priv->dev" instead of "priv->wlan_dev.netdev"

Changed two occurences of "((wlan_private *) dev->priv)->wlan_dev.netdev"
into "dev", because I didn't see the point in doing pointer-ping-pong.

The variables "ioport", "upld_rcv" and "upld_type" where unused. They have
been removed.
