ixgbe: dcb: IEEE PFC stats and reset logic incorrect

Browse source

PFC stats are only tabulated when PFC is enabled. However in IEEE
mode the ieee_pfc pfc_tc bits were not checked and the calculation
was aborted.

This results in statistics not being reported through ethtool and
possible a false Tx hang occurring when receiving pause frames.
