vhost-vdpa: mute unaligned memory error report
With TPM CRM device, vhost-vdpa reports an error when it tries
to register a listener for a non aligned memory region:
qemu-system-x86_64: vhost_vdpa_listener_region_add received unaligned region
qemu-system-x86_64: vhost_vdpa_listener_region_del received unaligned region
This error can be confusing for the user whereas we only need to skip
the region (as it's already done after the error_report())
Rather than introducing a special case for TPM CRB memory section
to not display the message in this case, simply replace the
error_report() by a trace function (with more information, like the
memory region name).
