[PATCH for-5.2] spapr: Avoid some integer conversions in spapr_phb_realize()

[Greg Kurz]

Without this patch, the irq number gets converted uselessly from int
to int32_t, back and forth.

This doesn't fix an actual issue, it's just to make the code neater.

This is a follow-up to my previous "spapr: Simplify error handling in
spapr_phb_realize()" patch. Maybe worth squashing it there ?
