[PATCH] net: dsa: Fix conditional handling of Wake-on-Lan configuration in dsa_user_set_wol

[Mohammed Anees]

The WOL configuration now checks if the DSA switch supports setting WOL
before attempting to apply settings via phylink. This prevents
unnecessary calls to phylink_ethtool_set_wol when WOL is not supported.
