qvirtqueue_setup() allocates the vring and virtqueue state. So far
there has been no function to free it. Callers have been using
guest_free() for the vring but forgot to free the QVirtQueue state.
This patch solves the memory leak by introducing qvirtqueue_cleanup().

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.

The MSIX interrupt was always acked without checking its value, which caused a
race condition. If the ISR was raised between the read and the acking, the ISR
was never detected and it timed out.
