iwlwifi: fix skb usage after free
commit b25026981aecde3685dd0e45ad980fff9f528daa upstream.

iwlwifi: sanity check before counting number of tfds can be free
we use skb->data after calling ieee80211_tx_status_irqsafe(), which
could free skb instantly.
On current kernels I do not observe practical problems related with
bug, but on 2.6.35.y it cause random system hangs when stressing
wireless link.
