Public bug reported:
We have a warning[1] in dmesg shows hns register napi as weight 256 but
not recommended. According to this commit[2] we shall use weight 64 as
suggested.
To cherry-pick this makes hns driver has reasonable weight

net: hns: Use NAPI_POLL_WEIGHT for hns driver
When the HNS driver loaded, always have an error print:
"netif_napi_add() called with weight 256"
This is because the kernel checks the NAPI polling weights
requested by drivers and it prints an error message if a driver
requests a weight bigger than 64.
So use NAPI_POLL_WEIGHT to fix it.
