scsi: Revert "scsi: hisi_sas: Drain bcast events in hisi_sas_rescan_topology()"
This reverts commit 11ff0c98fca35df16c84d4eee52008faecaf10a6.
Draining or flushing events in hisi_sas_rescan_topology() can hang the
driver, typically with phy up or phy down events being processed,
i.e. sas_porte_bytes_dmaed() or sas_phye_loss_of_signal().
