Subject: [PATCH] compat_ioctl: add compat handler for PPPIOCGL2TPSTATS

fixes following error seen on x86_64 kernel:
ioctl32(openl2tpd:7480): Unknown cmd fd(14) cmd(80487436){t:'t';sz:72} arg(ffa7e6c0) on socket:[105094]

The argument (struct pppol2tp_ioc_stats) uses "aligned_u64" and thus doesn't need
fixups.
