Dan Carpenter 6fc72c1b88 drm/amdgpu: fix integer overflow test in amdgpu_bo_list_create()
[ Upstream commit ff30e9e850 ]

We accidentally left out the size of the amdgpu_bo_list struct.  It
could lead to memory corruption on 32 bit systems.  You'd have to
pick the absolute maximum and set "num_entries == 59652323" then size
would wrap to 16 bytes.

Fixes: 920990cb08 ("drm/amdgpu: allocate the bo_list array after the list")
