x86/paravirt: Fix build PARAVIRT_XXL=y without XEN_PV
Kernel fails to compile with PARAVIRT_XXL=y if XEN_PV is not enabled:
ld.lld: error: undefined symbol: xen_iret
It happens because INTERRUPT_RETURN defined to use xen_iret if
CONFIG_PARAVIRT_XXL enabled regardless of CONFIG_XEN_PV.
The issue is not visible in the current kernel because CONFIG_XEN_PV is
the only user of CONFIG_PARAVIRT_XXL and there's no way to enable them
separately.
Rework code to define INTERRUPT_RETURN based on CONFIG_XEN_PV, not
CONFIG_PARAVIRT_XXL.
