[PATCH] Revert ide softirq handling
There's a problem with the REQ_BLOCK_PC handling as well (bad ->data_len
handling) where it could actually complete a request ahead of time. I
suggest we just back this out for now, I will resubmit it later when I'm
fully confident in it.
This reverts commit 8672d57138b34447719cd7749f3d21070e1175a1
