vhost: Fix ioctl # for VHOST_[GS]ET_FORK_FROM_OWNER
[ Upstream commit 24fc631539cc78225f5c61f99c7666fcff48024d ]
The VHOST_[GS]ET_FEATURES_ARRAY ioctl already took 0x83 and it would
result in a build error when the vhost uapi header is used for perf tool
build like below.
In file included from trace/beauty/ioctl.c:93:
tools/perf/trace/beauty/generated/ioctl/vhost_virtio_ioctl_array.c: In function ‘ioctl__scnprintf_vhost_virtio_cmd’:
tools/perf/trace/beauty/generated/ioctl/vhost_virtio_ioctl_array.c:36:18: error: initialized field overwritten [-Werror=override-init]
36 | [0x83] = "SET_FORK_FROM_OWNER",
| ^~~~~~~~~~~~~~~~~~~~~
tools/perf/trace/beauty/generated/ioctl/vhost_virtio_ioctl_array.c:36:18: note: (near initialization for ‘vhost_virtio_ioctl_cmds[131]’)
Fixes: 7d9896e9f6d02d8a ("vhost: Reintroduce kthread API and add mode selection")
