Stefan Haberland 9dffede011 s390/dasd: fix missing path conf_data after failed allocation
dasd_eckd_path_available_action() does a memory allocation to store
the per path configuration data permanently.
In the unlikely case that this allocation fails there is no conf_data
stored for the corresponding path.

This is OK since this is not necessary for an operational path but some
features like control unit initiated reconfiguration (CUIR) do not work.

To fix this add the path to the 'to be verified pathmask' again and
schedule the handler again.
