Fix build without CONFIG_XEN_EMU 

Upstream commit ddf0fd9ae1 "hw/xen: Support HVM_PARAM_CALLBACK_TYPE_GSI callback"
added kvm_xen_maybe_deassert_callback usage to target/i386/kvm/kvm.c file without
conditional preprocessing check. This breaks any build not using CONFIG_XEN_EMU.

Protect call by conditional preprocessing to allow build without CONFIG_XEN_EMU.
