[roll] Roll fuchsia [netdevice] Remove ports if only salt matches

There is a race condition during a netdevice port flap:
- The old port is destroyed by the device.
- Netdevice go client finds out and deregisters the port from its ports
map.
- The new port is ready and found by netcfg.
- Netcfg tries to create a new interface but netstack hasn't removed the
old one because it's blocking on some goroutines of the old interface.
- Netstack creates the new interface under a new name and registers its
port into the netdevice client's port map (it has the same base port id
as the old one).
- Now all the goroutines of the old interface has stopped and it went
forward to remove the interface which will again, try to deregister
itself again from ports map (ports#Close). Because it only compares the
base id, it causes the newly registered port to be removed.
- We see an excess amount of "unknown port" error logs.

Calling port#Close multiple times isn't the issue because the method is
carefully written to be idempotent. This change fixes the issue by
consulting the salt before removing the port entry.
