net: dsa: mv88e6xxx: Fix u64 statistics
[ Upstream commit 6e46e2d821bb22b285ae8187959096b65d063b0d ]
The switch maintains u64 counters for the number of octets sent and
received. These are kept as two u32's which need to be combined. Fix
the combing, which wrongly worked on u16's.
Fixes: 80c4627b2719 ("dsa: mv88x6xxx: Refactor getting a single statistic")
