net: phy: deal properly with autoneg incomplete in genphy_c45_read_lpa
The link partner advertisement registers are not guaranteed to contain
valid values if autoneg is incomplete. Therefore, if
MDIO_AN_STAT1_COMPLETE isn't set, let's clear all link partner
capability bits. This also avoids unnecessary register reads if link
is down and phylib is in polling mode.
