Subject: brcmfmac: fix memleak due to calling brcmf_sdiod_sgtable_alloc() twice

From: Arend Van Spriel <[email protected]>

commit 5f5d03143de5e0c593da4ab18fc6393c2815e108 upstream.

Due to a bugfix in wireless tree and the commit mentioned below a merge was needed which went haywire. So the submitted change resulted in the function brcmf_sdiod_sgtable_alloc() being called twice during the probe thus leaking the memory of the first call.
