<div class='commit-subject'>PCI/MSI: pci-xgene-msi: Fix CPU hotplug registration handling</div><div class='commit-msg'>The conversion to the new hotplug state machine introduced a regression
where a successful hotplug registration would be treated as an error,
effectively disabling the MSI driver forever.

Fix it by doing the proper check on the return value.
