brcmf_usb_probe_phase2() allocates resource for dev with brcmf_alloc(). The related resource should be released when the function gets some error. But when brcmf_attach() fails, relevant resource is not released, which will lead to resource leak. Fix it by calling brcmf_free() when brcmf_attach() fails.
