[ Upstream commit 8392df5d7e0b6a7d21440da1fc259f9938f4dec3 ]

In ath10k_htc_send_bundle, the bundle_skb could be freed by
dev_kfree_skb_any(bundle_skb). But the bundle_skb is used later
by bundle_skb->len.

As skb_len = bundle_skb->len, my patch replaces bundle_skb->len to
skb_len after the bundle_skb was freed.

Fixes: c8334512f3dd1 ("ath10k: add htt TX bundle for sdio")
