- Rearrange code inside ScsiPortStartIo() routine (some code for dma-support added, but currently disabled), also change time when spinlock is being held.

- Respective changes in ScsiPortStartPacket(), also some code is missing for rare kind of requests.
- Add flags check into ScsiPortIsr(), so that we skip unwanted interrupts (and change to usage of the new interrupt flags structure instead of a strange and unclear "IrpFlags" field).
