Check error code of get_cylider_idx_by_use()

Browse source 
If not cylinder with type DILUENT or OXYGEN is defined, this function
returns -1 which should not be used as an index to an array. This
patch adds code to check for this return value and exit gracefully.

On line I marked with a comment. Someone more knowledgeable of that part of
code than me should double check that return is here what we want.

[Dirk Hohndel: fixed small oversight...]
