net: hns3: allocate fd counter for queue bonding

driver inclusion
category:feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I62HX2

----------------------------------------------------------------------

For the fd rule of queue bonding is created by hardware
automatically, the driver needs to specify the fd counter
for each function, then it's available to query how many
times the queue bonding fd rules hit.
