The handle and addr fields of drm_xe_sync is defined as the union:
union {
__u32 handle;
__u64 addr;
};
When initialized on the stack on certain implementations, setting
.handle will leave the upper bits of .addr/the overall union
uninitialized causing exec calls to fail with:
[drm:xe_sync_entry_parse [xe]] Ioctl argument check failed at drivers/gpu/drm/xe/xe_sync.c:136: upper_32_bits(sync_in.addr)
Somewhat awkward but init .addr first to 0 and then set the handle after
the struct init.
