This reverts commit c65259a9b6e5380ac963944b69949ceb71ae623a.

The original commit 7521e0cf9e88 ("ofproto-dpif: Let the dpif report
when a port is a duplicate.") relies on the kernel to check if the
port exists or not. However, the current kernel code doesn't handle
when the port is moved to another network namespace.
