Dan Carpenter 335f1e797c drm/amdgpu: Fix integer overflow in amdgpu_gem_add_input_fence() ...

The "num_syncobj_handles" is a u32 value that comes from the user via the
ioctl.  On 32bit systems the "sizeof(uint32_t) * num_syncobj_handles"
multiplication can have an integer overflow.  Use size_mul() to fix that.
