Subject: [PATCH] I/OAT: Tighten descriptor setup performance

The change to the async_tx interface cost this driver some performance by
spreading the descriptor setup across several functions, including multiple
passes over the new descriptor chain.  Here we bring the work back into one
primary function and only do one pass.
