Instead of keeping a counter that is independent of the queue's data structure. Just use the queue's built-in counter. Ensure that it's pthread safe by keeping it wrapped inside the mutex for adding/deleting to the queue. Signed-off-by: Donald Sharp <sharpd@nvidia.com>

#### Why I did it
Reduce high CPU usage on zebra after performing port toggle on all interfaces simultaneously
#### How I did it
Apply zebra fpm backpressure patches from FRR mainline to dplane_fpm_sonic:
* zebra: Use built in data structure counter (FRRouting/frr#16221)
* Zebra fpm backpressure (FRRouting/frr#16220)
<!--
#### How to verify it
If PR needs to be backported, then the PR must be tested against the base branch and the earliest backport release branch and provide tested image version on these two branches. For example, if the PR is requested for master, 202211 and 202012, then the requester needs to provide test results on master and 202012.
