Subject: [PATCH] increase size of buffer_pool

- This solves an issue where in the worst-case an RLC AM instance would
  block because no new data nor control PDUs could be created to flush
  the buffers, effectivly causing a system stall.
- Happens in RLC AM stress test regularly with higher drop rates.
