  These API's were modified as part of commit id

Only 82xx adapter advertises QLCNIC_FW_CAPABILITY_MORE_CAPS bit.
Reading this bit from 83xx adapter causes the driver to skip
extra capabilities registers.

Because of this, driver was not issuing qlcnic_fw_cmd_set_drv_version()
for 83xx adapter.

This bug was introduced in commit 8af3f33d
 ("qlcnic: Add support for 'set driver version' in 83XX").

Since commit 82dc3c63 ("net: introduce NAPI_POLL_WEIGHT")
netif_napi_add() produces an error message if a NAPI poll weight
greater than 64 is requested.

qlcnic requests the weight as large as 256 for some of its rings, and
smaller values for other rings. For instance in qlcnic_82xx_napi_add()
I think the intention was to give the tx+rx ring a bigger weight than
to rx-only rings, but it's actually doing the opposite. So I'm assuming
the weights do not really matter much.

Just use the standard NAPI weights for all rings.
