openvswitch: Return vport module ref before destruction
Return module reference before invoking the respective vport
->destroy() function. This is needed as ovs_vport_del() is not
invoked inside an RCU read side critical section so the kfree
can occur immediately before returning to ovs_vport_del().
Returning the module reference before ->destroy() is safe because
the module unregistration is blocked on ovs_lock which we hold
while destroying the datapath.
