brcmfmac: testing the wrong variable in brcmf_rx_hdrpull()

Browse source 
Smatch complains about this code:

    drivers/net/wireless/broadcom/brcm80211/brcmfmac/core.c:335 brcmf_rx_hdrpull()
    error: we previously assumed '*ifp' could be null (see line 333)

The problem is that we recently changed these from "ifp" to "*ifp" but
there was one that we didn't update.

-       if (ret || !ifp || !ifp->ndev) {
+       if (ret || !(*ifp) || !(*ifp)->ndev) {
                if (ret != -ENODATA && ifp)
                                       ^^^
-                       ifp->stats.rx_errors++;
+                       (*ifp)->stats.rx_errors++;

I have updated it to *ifp as well.  We always call this function is a
non-NULL "ifp" pointer, btw.
