[PATCH] staging/wlan-ng/hfa384x: Delete an unnecessary check before the macro call âdev_kfree_skbâ

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>

The dev_kfree_skb() function performs also input parameter validation.
Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
