vhost-vdpa: change ioctl # for VDPA_GET_VRING_SIZE

VDPA_GET_VRING_SIZE by mistake uses the already occupied
ioctl # 0x80 and we never noticed - it happens to work
because the direction and size are different, but confuses
tools such as perf which like to look at just the number,
and breaks the extra robustness of the ioctl numbering macros.

To fix, sort the entries and renumber the ioctl - not too late
since it wasn't in any released kernels yet.
