ofproto-dpif-xlate: Reduce stack usage in recursive xlate functions.

Several xlate actions used in recursive translation currently store a
large amount of information on the stack. This can result in handler
threads quickly running out of stack space despite before
xlate_resubmit_resource_check() is able to terminate translation. This
patch reduces stack usage by over 3kb from several translation actions.

This patch also moves some trace function from do_xlate_actions into its
own function.
