  ofproto-dpif: Reduce the time to create many bridges.

This patch moves xlate_txn_start() and xlate_txn_commit() out of the loop
traversing all the ofproto-dpifs to reduce the time of creating a large mount
of bridges in separate database transactions.  As a global variable, new_xcfg
should only be allocated at the beginning and commited at the end once time,
rather than doing it repeatedly in the loop body.
