  1. Accelerate CSR->Ell,Hybrid conversions on CUDA. 

    + The previous grid dimensions for `initialize_zero_ell` were `stride *
  num_rows`, i.e. roughly the dense matrix dimension.
+ Using `max_nnz_per_row * num_rows` reduces significantly the amount of threads
  created which makes this kernel call more efficient (less useless thread
  creation).
