[BUG] Building error in user/cuda/ktmig.cu

[Shikonin]

I got same error as #285 when building user/cuda/ktmig.cu. It seems that CUDA 12.0 removed support for texture references.

code version 8afd0fa

Linux 5.10.60.1-microsoft-standard-WSL2
Python 3.11.2
gcc (Debian 12.2.0-14) 12.2.0
nvcc --version
Built on Mon_Apr__3_17:16:06_PDT_2023
