[net-next 07/13] ice: SW DCB, report correct max TC value

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: Dave Ertman <david.m.ertman@intel.com>

lldpad is using the value reported in the DCB config for
max_tc as the max allowed number of TCs, not the current
max.  ICE driver was reporting it as current maximum TC.

Change DCB_NL function to report maximum TC allowed by
this device.
