net: amend the fix for SO_BSDCOMPAT gsopt infoleak

The fix for CVE-2009-0676 (upstream commit df0bca04

) is incomplete. Note
that the same problem of leaking kernel memory will reappear if someone
on some architecture uses struct timeval with some internal padding (for
example tv_sec 64-bit and tv_usec 32-bit) --- then, you are going to
leak the padded bytes to userspace.
