Latest MSVS breaks build on windows

Description

When building on Windows (MSVC, MSYS2) with Nvidia HW support, MSVC 16.9 breaks the process, NVCC (CUDA dev version 11.2) is complaining about 

libavfilter/vf_scale_cuda_bicubic.cu(101): error: calling a __host__ function("__floorf") from a __device__ function("Subsample_Bicubic<unsigned char> ") is not allowed

libavfilter/vf_scale_cuda_bicubic.cu(101): error: identifier "__floorf" is undefined in device code

Changing the four floor calls to floorf in libavfilter/vf_scale_cuda_bicubic.cu as suggested here
​https://devtalk.blender.org/t/cuda-compile-error-windows-10/17886/4
seems to do the business. Builds fine and the filter works.

Being a bit green when it comes to development and contributing, I hope that someone with more experience could provide a patch.

Best regards
Alexander
