Make retries obey host_self_blocked flag #2

Lets try this again, this time with the patch attached....

The following patch against 2.6.2 will prevent the midlayer from issuing retries if host_self_blocked is set. This was raised as an issue here:

I'm trying to improve and extend scsi_block_requests, and this is the first, and hopefully least controversial, step.
