net: mscc: ocelot: fix race between ndo_get_stats64 and ocelot_check_stats_work
The 2 methods can run concurrently, and one will change the window of
counters (SYS_STAT_CFG_STAT_VIEW) that the other sees. The fix is
similar to what commit 7fbf6795d127 ("net: mscc: ocelot: fix mutex lock
error during ethtool stats read") has done for ethtool -S.
Fixes: a556c76adc05 ("net: mscc: Add initial Ocelot switch support")
