    KVM: arm64: Reject VM creation when the default IPA size is unsupported

    BugLink: https://bugs.launchpad.net/bugs/1925259

    commit 7d717558dd5ef10d28866750d5c24ff892ea3778 upstream.

    KVM/arm64 has forever used a 40bit default IPA space, partially
    due to its 32bit heritage (where the only choice is 40bit).
    ...

This adds an -EINVAL exit with the following message logged (visible in the rport):
