[PATCH] net: brcmfmac: fix potential resource leak in brcmf_usb_probe_phase2()

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.
