net: hns3: fix reset timeout under full functions and queues

The cmdq reset command times out when all VFs are enabled and the queue is
full. The hardware processing time exceeds the timeout set by the driver.
In order to avoid the above extreme situations, the driver extends the
reset timeout to 1 second.
