Use the existing offsetof() macro instead of duplicating code.

# Form letter - net-next is closed
We have already sent the networking pull request for 5.11 and therefore
net-next is closed for new drivers, features, code refactoring and
optimizations. We are currently accepting bug fixes only.
Please repost when net-next reopens after 5.11-rc1 is cut.
Look out for the announcement on the mailing list or check:
http://vger.kernel.org/~davem/net-next.html
RFC patches sent for review only are obviously welcome at any time.
