Subject: [PATCH 03/26] net/hns3: fix delay for waiting to stop Rx/Tx
When the primary process executes dev_stop or is being reset, the packet
sending and receiving functions is changed. In this moment, the primary
process requests secondary processes to change their Rx/Tx functions, and
delays a period of time in case of crashes when queues are still in use.
The delay time depends on the number of queues actually used, instead of
the maximum number of queues supported by the device.
Fixes: 23d4b61fee5d ("net/hns3: support multiple process")
