[PATCH AUTOSEL 6.1 04/41] drm/amdgpu: Fix integer overflow in amdgpu_cs_pass1

[Sasha Levin]

From: hackyzh002 <hackyzh002 at gmail.com>

[ Upstream commit 87c2213e85bd81e4a9a4d0880c256568794ae388 ]

The type of size is unsigned int, if size is 0x40000000, there will
be an integer overflow, size will be zero after size *= sizeof(uint32_t),
will cause uninitialized memory to be referenced later.
