The recent adding of multicall debug mixed up the referencing of
the debug data. A __percpu tagged pointer can't be initialized with a

IIUIC we only need data until SMP is initialized, so setting per-cpu
pointer just on cpu0 may be sufficient. Not sure where to do this though.
But this works as well.
