Assigning ssp_task.retry_count to itself has no effect

This begs the question of what the original author intended to write.


If you check commit 86344494e364, I got rid off sas_task.retry_count as it was never used. This means that we explicitly set scb->ata_task.retry_count to zero now.

I guess that they wanted to something like that for scb->ssp_task, but there was no sas_task member to copy from.

The value in scb->ssp_task.retry_count would be zero from asd_ascb_alloc() -> asd_init_ascb(). So dropping this self-assigned code should be ok. However, it would be nice to have consistent code for all protocol frame types, so we could get rid of setting scb->ata_task.retry_count = 0 also.
