libqos: drop duplicated virtio_ring.h bit definitions
Note that virtio_ring.h defines feature bits using their bit number:
#define VIRTIO_RING_F_INDIRECT_DESC 28
On the other hand libqos virtio.h uses the bit mask:
#define QVIRTIO_F_RING_INDIRECT_DESC 0x10000000
The patch makes the necessary adjustments.
I have used "1u << BITMASK" instead of "1ULL << BITMASK" because the
64-bit feature fields are not implemented in libqos virtio.
