PCI: xgene-msi: Make per-CPU interrupt setup robust
The way the per-CPU interrupts are dealt with in the XGene MSI
driver isn't great:
- the affinity is set after the interrupt is enabled
- nothing prevents userspace from moving the interrupt around
- the affinity setting code pointlessly allocates memory
- the driver checks for conditions that cannot possibly happen
Address all of this in one go, resulting in slightly simpler setup
code.
