Jiawen Wu 0360c23f64 net/ngbe: fix missed link interrupt 
When the port is started and stopped continuously and quickly, one
interrupt cannot be handled in time, which will cause subsequent
interrupts to be lost, so that link status will cannot be updated.

Fixes: b9246b8fa2 ("net/ngbe: support link update")
