net: ena: fix continuous keep-alive resets
last_keep_alive_jiffies is updated in probe and when a keep-alive event is received. In case the driver times-out on a keep-alive event, it has high chances of continuously timing-out on keep-alive events. This is because when the driver recovers from the keep-alive-timeout reset the value of last_keep_alive_jiffies is very old, and if a keep-alive event is not received before the next timer expires, the value of last_keep_alive_jiffies will cause another keep-alive-timeout reset and so forth in a loop. Solution: Update last_keep_alive_jiffies whenever the device is restored after reset.
