Greg Kurz f9b43958b9 spapr: Simplify error path of spapr_core_plug()
spapr_core_pre_plug() already guarantees that the slot for the given core
ID is available. It is thus safe to assume that spapr_find_cpu_slot()
returns a slot during plug. Turn the error path into an assertion.
It is also safe to assume that no device is attached to the corresponding
DRC and that spapr_drc_attach() shouldn't fail.

Pass &error_abort to spapr_drc_attach() and simplify error handling.
