Fixes regression in #9295. It seems cuda_fp16.h bundled with CUDA 12.4.0 has a problem and causing the following error:

https://ci.preferred.jp/cupy.linux.cuda124/198208/

ptxas fatal   : Unresolved extern function '_ZN6__halfC1Ef'

I locally confirmed this is fixed in CUDA 12.4.1.

cuda_fp16.h bundled with CUDA 12.4.0 causes the following error:

Confirmed CI issue resolved. Error shown is timeout and is irrelevant.
