[PATCH net-next v1 1/8] net: ieee8021q: print traffic type and queue count with %u

[Oleksij Rempel <o.rempel@pengutronix.de>]

Switch the out-of-range diagnostic in ieee8021q_tt_to_tc() from %d to
%u. The traffic class count num_queues is an unsigned int and the
traffic type is an enumeration, so printing them as unsigned matches
their types. The print sits on the range-check error path, which still
rejects a negative traffic type; %u only changes how an out-of-range
value is rendered, not which values are rejected.

Preparation for the inverse helper added next, which follows the same
convention.
