Wrong matrix subtyping in cuSPARSE #3104

@gdalle

Description

@gdalle

Describe the bug

Not all sparse matrices in cuSPARSE subtype AbstractCuSparseMatrix.

To reproduce

The Minimal Working Example (MWE) for this bug:

julia> using cuSPARSE  # v6

julia> subtypes(cuSPARSE.AbstractCuSparseMatrix)
2-element Vector{Any}:
 cuSPARSE.CuSparseMatrixBSR
 cuSPARSE.CuSparseMatrixCOO

julia> cuSPARSE.CuSparseMatrixCSR isa cuSPARSE.AbstractCuSparseMatrix
false
