[SCSI] zfcp: Move qdio setup from erp to zfcp_qdio.c
Initialization of the qdio waitqueue should happen when the qdio data is initialized and the QDIOUP flag should be handled in the qdio code as well. Adjust the code accordingly and remove the superfluos function zfcp_erp_adapter_strategy_open_qdio.
