x86/irq/32: Invoke irq_ctx_init() from init_IRQ()
irq_ctx_init() is invoked from native_init_IRQ() or from xen_init_IRQ() code. There is no reason to have this split. The interrupt stacks must be allocated no matter what.
Invoke it from init_IRQ() before invoking the native or XEN init implementation.
