[PATCH] wifi: ath: Use dev_kfree_skb_any(skb) call only once in three functions

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>

A dev_kfree_skb_any(skb) call was immediately used after a return code
check in three function implementations.
Thus use such a function call only once instead directly before the checks.

This issue was transformed by using the Coccinelle software.
