[dpdk-dev] [PATCH v2] virtio: enable indirect descriptors feature

Indirect descriptors support was disabled by commit 4a92b67151be11,
presumably by accident as it was correctly supported.

This patch simply adds VIRTIO_RING_F_INDIRECT_DESC back to
the supported features bit mask, hence enabling the use of
indirect descriptors when the feature is negociated with the
device.
