Commit 84d582d236dc ("xen: Revert commits da72ff5bfcb0 and
72a9b186292d") 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.
