There is no need to clear the external_mac if DVR is enabled, not
even when the port is down. This patch ensures the external_mac is
only deleted when DVR is not enabled.
Without this patch, if a VM with a floating IP gets deleted, and
DVR is enabled, during some time the traffic gets (wrongly)
centralized while it should not. And it is also generating more
load on the OVN side unnecesarily.

The external_mac entry in the NAT table is used to distribute/centralize
|
|
the traffic to the FIPs. When there is an external_mac set the traffic
|
|
is distributed (DVR). When it is empty it is centralized through the
|
|
gateway port (no DVR). Upon port status transition to down, the
|
|
external_mac was removed regardless of DVR being enabled or not, leading
|
|
to centralize the FIP traffic for DVR -- though it was for down ports that
|
|
won't accept traffic anyway.
