r8152: Avoid memcpy() over-reading of ETH_SS_STATS

[ Upstream commit 99718abdc00e86e4f286dd836408e2834886c16e ]

In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally reading across neighboring array fields.

The memcpy() is copying the entire structure, not just the first array.
Adjust the source argument so the compiler can do appropriate bounds
checking.
