Avoid use of numel in sparse matrix min/max functions
* dSparse.cc (SparseMatrix SparseMatrix::max (Array<octave_idx-type>&, int)) :
Remove use of numel
(SparseMatrix SparseMatrix::min (Array<octave_idx-type>&, int)) : ditto
* CSparse.cc (SparseComplexMatrix SparseComplexMatrix::max (
Array<octave_idx-type>&, int)) : Remove use of numel
(SparseComplexMatrix SparseComplexMatrix::min (Array<octave_idx-type>&,
int)) : ditto
