net: qos offload add flow status with dropped count
This patch adds a drop frames counter to tc flower offloading.

Some actions like police action and the coming introduced stream gate
action would produce dropped frames which is necessary for user. Status
update shows how many filtered packets increasing and how many dropped
in those packets.
