upcall: Remove redundant xlate_actions_for_side_effects().

As a result of commit a0bab87 (ofproto: Remove per-flow miss hash
table from upcall handler.) we're guaranteed that every packet has had
xlate_actions() called on it at least once.  Therefore, there's no
need to re-xlate slow path flows just to shove their packets through
the system.

This also may fix a bug discussed here:
