xen/pciback: Don't print scary messages when unsupported by hypervisor.
We print at the warninig level messages such as: pciback 0000:90:00.5: MSI-X preparation failed (-38) which is due to the hypervisor not supporting this sub-hypercall (which was added in Xen 4.3). Instead of having scary messages all the time - only have it when the hypercall is actually supported. Signed-off-by:Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Signed-off-by:
