xen: Move xen_have_vector_callback definition to enlighten.c

Commit 84d582d ("xen: Revert commits da72ff5 and 72a9b18") defined xen_have_vector_callback in enlighten_hvm.c. Since guest-type-neutral code refers to this variable this causes build failures when CONFIG_XEN_PVHVM is not defined. Moving xen_have_vector_callback definition to enlighten.c resolves this issue.
