[PATCH] vhost-vdpa: skip TPM CRB memory section

[marcandre . lureau]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

851d6d1a0f ("vfio/common: remove spurious tpm-crb-cmd misalignment
warning") removed the warning on vfio_listener_region_add() path.

An error is reported for vhost-vdpa case:
qemu-kvm: vhost_vdpa_listener_region_add received unaligned region

Skip the CRB device.

Fixes:
