[PATCH] amdgpu: fix integer overflow on 32-bit architectures

Multiplying 10 by four overruns a 'long' variable, as clang points out: drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:4160:53: error: overflow in expression; result is -294967296 with type 'long' [-Werror,-Winteger-overflow] expires = ktime_get_mono_fast_ns() + NSEC_PER_SEC *
