mwl8k: Fix a double Free in mwl8k_probe_hw
[ Upstream commit a8e083ee8e2a6c94c29733835adae8bf5b832748 ]
In mwl8k_probe_hw, hw->priv->txq is freed at the first time by
dma_free_coherent() in the call chain:
if(!priv->ap_fw)->mwl8k_init_txqs(hw)->mwl8k_txq_init(hw, i).
Then in err_free_queues of mwl8k_probe_hw, hw->priv->txq is freed
at the second time by mwl8k_txq_deinit(hw, i)->dma_free_coherent().
My patch set txq->txd to NULL after the first free to avoid the
double free.
