xen: events: remove dom0 specific xen_create_msi_irq
The function name does not distinguish it from xen_allocate_pirq_msi (which operates on domU and pvhvm domains rather than dom0). Hoist domain 0 specific functionality up into the only caller leaving functionality common to all guest types in xen_bind_pirq_msi_to_irq.
