slob: Fix early boot kernel crash

Browse Source 
Commit fd3142a59af2012a7c5dc72ec97a4935ff1c5fc6 broke
slob since a piece of a change for a later patch slipped into
it.

Fengguang Wu writes:

  The commit crashes the kernel w/o any dmesg output (the attached one is
  created by the script as a summary for that run). This is very
  reproducible in kvm for the attached config.
