net: phy: marvell: Align set_loopback() implementation
Use genphy_loopback() to disable loopback like ksz9031_set_loopback().
This way disable loopback is implemented only once within
genphy_loopback() and the set_loopback() implementations look similar.
Also fix comment about msleep() in the out-of loopback case which is not
executed in the out-of loopback case.
