[PATCH v2 1/6] zorro_esp: Limit DMA transfers to 65535 bytes

The core driver, esp_scsi, does not use the ESP_CONFIG2_FENAB bit, so the chip's Transfer Counter register is only 16 bits wide (not 24). A larger transfer cannot work and will theoretically result in a failed command and a "DMA length is zero" error. Fixes: 3109e5ae0311 Signed-off-by: Finn Thain
