Do not use memcpy() which is not safe, but instead use strncpy() which
will make sure that the string is NUL terminated (in the Linux
implementation) if the string is smaller than the length specified. This
fixes KASAN out of bounds warnings while fetching port statistics.
Fixes: f5e2ed022dff ("dsa: mv88e6xxx: Add Second back of statistics")I'm sure it goes back much further than that.
