Greg Kurz 5d0fb1508e spapr: consolidate the VCPU id numbering logic in a single place 
Several places in the code need to calculate a VCPU id:

    (cpu_index / smp_threads) * spapr->vsmt + cpu_index % smp_threads
    (core_id / smp_threads) * spapr->vsmt (1 user)
    index * spapr->vsmt (2 users)

or guess that the VCPU id of a given VCPU is the first thread of a virtual
core:

    index % spapr->vsmt != 0

Even if the numbering logic isn't that complex, it is rather fragile to
have these assumptions open-coded in several places. FWIW this was
proved with recent issues related to VSMT.

This patch moves the VCPU id formula to a single function to be called
everywhere the code needs to compute one. It also adds an helper to
guess if a VCPU is the first thread of a VCORE.
