Fix detection of Xen sysctl version 9

In commit 371ddc98, I mistakenly added the check for sysctl
version 9 after setting the hypercall version to 1, which will
fail with

error : xenHypervisorDoV1Op:967 : Unable to issue hypervisor
ioctl 3166208: Function not implemented

This check should be included along with the others that use
hypercall version 2.
