This patch fixes an issue when the ipr daemons are stopped when tool_init() function is called on iprlib.c. When failing to open scsi_host class or read the scsi device model, the function called exit_on_error(), which killed the daemons in the process. This patch changes it to warning messages while performs 4 attempts to open scsi_host class or read the scsi device model.
