Dmitry Safonov 61f4b23769 netlink: Don't shift with UB on nlk->ngroups ... On i386 nlk->ngroups might be 32 or 0. Which leads to UB, resulting in hang during boot. Check for 0 ngroups and use (unsigned long long) as a type to shift. Fixes: 7acf9d4237 ("netlink: Do not subscribe to non-existent groups").
