[PATCH 7/8] n_gsm: replace kfree_skb w/ appropriate dev_* versions

[Alan Cox <alan@lxorguk.ukuu.org.uk>]

From: Russ Gorby <russ.gorby@intel.com>

Drivers are supposed to use the dev_* versions of the kfree_skb
interfaces. In a couple of cases we were called with IRQs
disabled as well which kfree_skb() does not expect.

Replaced kfree_skb calls w/ dev_kfree_skb and dev_kfree_skb_any
