Qi Zhang dd18b06a32 net/e1000: fix mailbox interrupt handler 
Mailbox interrupt handler only takecare of the PF reset notification,
for other message mbx->ops.read should not be called since it gets
chance to break the foreground VF to PF communication.

Fixes: 316f4f1adc ("net/igb: support VF mailbox interrupt for link up/down")
