Bareudp uses the TSTATS infrastructure (dev_sw_netstats_*()) for RX packet counters. It was also recently converted to use the device core stats (dev_core_stats_*()) for RX and TX drops (see commit 788d5d655bc9 ("bareudp: Use pcpu stats to update rx_dropped counter.")). Since core stats are to be avoided in drivers, and for consistency with VXLAN and Geneve, let's convert packet stats handling to DSTATS, which can handle RX/TX stats and packet drops. Statistics that don't fit DSTATS are still updated atomically with DEV_STATS_INC().
