perf/cxl: Split the MSI vector out of info->irq

info->irq means two different things depending on how far probe has got.
cxl_pmu_parse_caps() sets it to the MSI/MSI-X message number from the CPMU
Capability register. cxl_pmu_probe() passes that to pci_irq_vector() and
then overwrites it with the Linux virq, which is what the hotplug callbacks
hand to irq_set_affinity().

Both are ints called irq, so nothing catches a mix-up, and the valid ranges
differ. 0 is a fine message number but never a valid virq.

Give the message number its own field. No functional change.
