net: ethernet: sun: remove redundant variables adv and lpa and mii_reads
Variables adv and lpa are being assigned but are never used hence they
are redundant and can be removed. Also remove the unncessary mii_reads
too.
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]
