[MLDataDevices] `AbstractCuSparseArray` not defined in CUDA.jl v5.9.6

[AntonOresten]

The MLDataDevices CUDA extension doesn't compile with CUDA.jl v5.9.6 due to JuliaGPU/CUDA.jl#2942 removing AbstractCuSparseArray from CUDA.SPARSE, leaving only AbstractCuSparseMatrix and AbstractCuSparseVector, subtyping AbstractGPUSparseArray.
