[PATCH] wifi: brcmfmac: Fix potential kernel oops when probe fails

When probe of the sdio brcmfmac device fails for some reasons (i.e.
missing firmware), the sdiodev->bus is set to error instead of NULL, thus
the cleanup later in brcmf_sdio_remove() tries to free resources via
invalid bus pointer. Fix this.
