zebra: Limit queue depth in dplane_fpm_nl
The dplane providers have a concept of input queues
and output queues. These queues are chained together
during normal operation. The code in zebra also has
a feedback mechanism where the MetaQ will not run when
the first input queue is backed up. Having the dplane_fpm_nl
code grab all contexts when it is backed up prevents
this system from behaving appropriately.
Modify the code to not add to the dplane_fpm_nl's internal
queue when it is already full. This will allow the backpressure
to work appropriately in zebra proper.
