This fixes an important brcmfmac use-after-free error:
brcmfmac: change driver unbind order of the sdio function devices
commit 5c3de777bdaf48bd0cfb43097c0d0fb85056cab7 upstream.
commit 01b43f2e3cad60c626daa9b174667a202cee6987 in linux-4.14.y
Without this change, I notice this error regularly when loading the wifi
firmware on the nanopi neo air.
