qlcnic: Fix update of ethtool stats.
o Aggregating tx stats in adapter variable was resulting in
an increase in stats even after no traffic was run and
user runs ifconfig/ethtool command.
o qlcnic_update_stats used to accumulate stats in adapter
struct at each function call, instead accumulate tx stats
in local variable and then assign it to adapter structure.
