x86/smpboot: Set online before setting up vectors

There is no reason to set the CPU online after establishing the vectors on
the upcoming CPU. The vector space is protected by the vector lock so no
changes can happen.

Marking the CPU online before setting up the vector space makes tracing
work in the early vector management cpu online code.
