Since queues are not stopped anymore, management frames would be
dropped if the corresponding tx queue is full.
This can cause issues say when we want to setup an ampdu stream and
action frames i.e addba requests keep getting dropped frequently.
Fix this by reserving some buffers to allow management frames to
go through in queue full conditions.
