!557 net: hns3: modify reset delay time to avoid configuration timeout

Merge Pull Request from: @svishen 
 
Currently the vf function reset needs to delay 5000ms for stack recovery.
This is too long for product configurations and cause configuration failures. According to the tests, 500ms delay is enough for reset process except PF FLR. So this patch adapts this delay in these scenarios.
