net: ena: add jiffies of last napi call to stats
There are instances when we want to know when the last napi was
called for debugging.
On stuck / heavy loaded CPUs, the ena napi handler might not be
called for a long period of time. This stat can help us to
determine how much time passed since the last execution of napi.
