[PATCH 23/88] esp.c: don't immediately raise INTR_BS if SCSI data needed in esp_do_dma()

[Mark Cave-Ayland]

In the case when more data is requested from the SCSI layer during a DMA data
transfer from a device, don't immediately fall through to the TC check logic.
Otherwise when TC is zero INTR_BS will be raised immediately rather than when
the next set of SCSI data is ready.
