Subject: brcmfmac: Fix a memory leak in error handling path in 'brcmf_cfg80211_attach'

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.
