net: relax setup_tc ndo op handle restriction

I added this check in setup_tc to multiple drivers,

 if (handle != TC_H_ROOT || tc->type != TC_SETUP_MQPRIO)

Unfortunately restricting to TC_H_ROOT like this breaks the old
instantiation of mqprio to setup a hardware qdisc. This patch
relaxes the test to only check the type to make it equivalent
to the check before I broke it. With this the old instantiation
continues to work.

A good smoke test is to setup mqprio with,

# tc qdisc add dev eth4 root mqprio num_tc 8 \
  map 0 1 2 3 4 5 6 7 \
  queues 0@0 1@1 2@2 3@3 4@4 5@5 6@6 7@7

Fixes: e4c6734eaab9 ("net: rework ndo tc op to consume additional qdisc handle paramete")
