Thanks for noticing this issue. However it should be fixed differently.
This was introduced by Uwe's clean-up patch:

Okay, it is just one patch. I will apply it to my tree as well. Should
be good enough.

Six minor fixes to device drivers and one to the multipath alua
handler. The most extensive fix is the zfcp port remove prevention
one, but it's impact is only s390.
The patch is available here:

With the change to allow the boot CPU0 to be isolated, it is possible
to specify command line options that result in no housekeeping CPU
online at boot.
An 8 CPU system booted with "nohz_full=0-6 maxcpus=4", for example.
It is not easily possible at housekeeping init time to know all the
