Replace custom statistics tracking with the kernel's dstats infrastructure to simplify code and improve consistency with other network drivers. This change: - Sets dev->pcpu_stat_type = NETDEV_PCPU_STAT_DSTATS for automatic automatic allocation and deallocation. - Removes manual stats fields and their update - Replaces custom nsim_get_stats64() with dev_get_stats() - Uses dev_dstats_tx_add() and dev_dstats_tx_dropped() helpers - Eliminates the need for manual synchronization primitives The dstats framework provides the same functionality with less code.
