Title: pcl_cell: don't ignore the return value of the wrapped cell

This makes sure ecto actually stops processing in case one of the cells
produces an error and returns something else than ecto::OK.

At the moment cells wrapped by PclCell always return 0 (ecto::OK)
and cells depending on a cell whose process method failed are still called.
