Changed error message when trying to compute condition number of sparse matrix in 2-norm, suggesting 1 or Inf norm.

Newbies like me or https://discourse.julialang.org/t/condition-number-of-sparse-matrix/77131/5 got diverted into trying densifying the array, which is very limited in many applications...
