iproute2: improve mqprio inputs for queue offsets and counts

This changes mqprio input format to be more user friendly.

Old usage,

 # ./tc/tc qdisc add dev eth3 root mqprio help
Usage: ... mqprio [num_tc NUMBER] [map P0 P1...]
                  [offset txq0 txq1 ...] [count cnt0 cnt1 ...] [hw 1|0]

New usage,

 # ./tc/tc qdisc add dev eth3 root mqprio help
Usage: ... mqprio [num_tc NUMBER] [map P0 P1 ...]
                  [queues count1@offset1 count2@offset2 ...] [hw 1|0]
