#1691466 — [PATCH 4.9 23/72] brcmfmac: Fix a memory leak in error handling path in brcmf_cfg80211_attach

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christophe Jaillet <christophe.jaillet@wanadoo.fr>

commit 57c00f2fac512837f8de73474ec1f54020015bae upstream.

If 'wiphy_new()' fails, we leak 'ops'. Add a new label in the error
handling path to free it in such a case.

Fixes: 5c22fb85102a7 ("brcmfmac: add wowl gtk rekeying offload support")
