Subject: net/mlx5e: Check for qos capability in dcbnl_initialize

From: Huy Nguyen <[email protected]>

[ Upstream commit 33c52b6718d2a6cb414440c98560818910d896dc ]

qos capability is the master capability bit that determines if the DCBX is supported for the PCI function. If this bit is off, driver cannot run any dcbx code.
