net: phy: clear EEE runtime state in PHY_HALTED/PHY_ERROR 



Clear EEE runtime flags when the PHY transitions to HALTED or ERROR
and the state machine drops the link. This avoids stale EEE state being
reported via ethtool after the PHY is stopped or hits an error.

This change intentionally only clears software runtime flags and avoids
MDIO accesses in HALTED/ERROR. A follow-up patch will address other
link state variables.
