protocol/server: Print error-xlator name

Problem:
At the moment from which xlator the errors are stemming from is a mystery.

Fix:
With this patch we can find on the server side which xlator first gave
the errno received by server xlator. I am not yet sure how to get this
done for client side which has lot of copy_frame()s. May be another
patch.
