net: usb: lan78xx: don't modify phy_device state concurrently
[ Upstream commit 6b67d4d63edece1033972214704c04f36c5be89a ]
Currently phy_device state could be left in inconsistent state shown
by following alert message[1]. This is because phy_read_status could
be called concurrently from lan78xx_delayedwork, phy_state_machine and
__ethtool_get_link. Fix this by making sure that phy_device state is
updated atomically.
