From: Hendrik Brueckner <brueckner@xxxxxxxxxxxxxxxxxx>
If the iucv_path_connect() call fails then return an error code that
corresponds to the iucv_path_connect() failure condition; instead of
returning -ECONNREFUSED for any failure.
This helps to improve error handling for user space applications
(e.g. inform the user that the z/VM guest is not authorized to
connect to other guest virtual machines).
The error return codes are based on those described in connect(2).
