When an ethdev port is released, a destroy event is triggered to notify
the users about the released port.

A bit before the destroy event is triggered, the port becomes invalid
by changing its state to UNUSED and cleaning its data. Therefore, the
port is invalid for the destroy event callback process and the users
may get a wrong information of the port.

Move the destroy event emitting to be called before the port
invalidation.

Fixes: 133b54779aa1 ("ethdev: fix port data reset timing")
Fixes: 29aa41e36de7 ("ethdev: add notifications for probing and removal")
