Path verification is either done via dasd_eckd_read_conf() which is triggered during online processing and resume or via do_path_verification_work() which is triggered after path events. The dasd_eckd_read_conf() version added paths unconditionally and did not check if the path mask was empty. This led to devices having the disconnected stop flag set but a valid path mask. So they where not working although they had paths validated successfully. After a resume this state could even not be solved with additional paths added. Fix by checking for an empty path mask in dasd_eckd_read_conf() and clearing the device stop bits for a newly added channel path.
