KVM introduced internal error exit reason and suberror at the same time,
and later extended it with internal error data.
QEMU does not report suberror on hosts between these two events because
we check for the extension. (half a year in 2009, but it is misleading)
Fix by removing KVM_CAP_INTERNAL_ERROR_DATA condition on printf.
(partially improved by bb44e0d12df70 and ba4047cf848a3 in the past)

Applied to uq/master, thanks (please remember uq/master in the subject
line in the future).
