net: phy: marvell10g: fix usage of new MMD modifying helpers 

When replacing mv3310_modify() with phy_modify_mmd() we missed that
they behave differently, mv3310_modify() returns 1 on a changed
register value whilst phy_modify_mmd() returns 0. Fix this by replacing
phy_modify_mmd() with phy_modify_mmd_changed() where needed.

Fixes: b52c018ddc ("net: phy: make use of new MMD accessors")
