[PATCH] net: ethernet: sun: remove redundant variables adv and lpa

From: Colin Ian King <redacted>

Variables adv and lpa are being assigned but are never used hence they
are redundant and can be removed.

Cleans up clang warnings:
warning: variable 'lpa' set but not used [-Wunused-but-set-variable]
warning: variable 'adv' set but not used [-Wunused-but-set-variable]
