net: mvpp2: drop useless fields in mvpp2_bm_pool and related code
This commit drops dead code from the mvpp2 driver. The 'in_use' and 'in_use_thresh' fields of 'struct mvpp2_bm_pool' are incremented/decremented/initialized in various places. But they are only used in one place: if (is_recycle && (atomic_read(&bm_pool->in_use) < bm_pool->in_use_thresh)) return 0; However 'is_recycle', passed as argument to mvpp2_rx_refill() is always false. So in fact, this code is never reached, and the 'is_recycle' argument is useless. So let's drop this code.
