tg3: Update ethtool set_settings error checks

Browse Source 
The ethtool interface has acquired some new enumerations since the
tg3 driver's tg3_set_settings() error checking code was written.  The
error checking code is no longer complete.  This patch rewrites the
error checking so that it is future-proofed.
