Subject: [PATCH] virtio: enable indirect descriptors feature

Virtio indirect descriptors are supported by the data-path
but the feature bit is never set during feature negociation.

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.
