x86/vector/msi: Select CONFIG_GENERIC_IRQ_RESERVATION_MODE
Select CONFIG_GENERIC_IRQ_RESERVATION_MODE so PCI/MSI domains get the
MSI_FLAG_MUST_REACTIVATE flag set in pci_msi_create_irq_domain().
Remove the explicit setters of this flag in the apic/msi code as they are
not longer required.
Fixes: 4900be83602b ("x86/vector/msi: Switch to global reservation mode")
