[PATCH net-next v3 11/18] net: stmmac: remove priv->eee_tw_timer

["Russell King (Oracle)" <rmk+kernel@armlinux.org.uk>]

priv->eee_tw_timer is only assigned during initialisation to a
constant value (STMMAC_DEFAULT_TWT_LS) and then never changed.

Remove priv->eee_tw_timer, and instead use STMMAC_DEFAULT_TWT_LS
for both uses in stmmac_eee_init().
