xen: fold xen_sysexit into xen_iret xen_sysexit and xen_iret were doing essentially the same thing. Rather than having a separate implementation for xen_sysexit, we can just strip the stack back to an iret frame and jump into xen_iret. This removes a lot of code and complexity - specifically, another critical region.
