KSZ9131 will not work with some switches due to workaround for KSZ9031
introduced in commit d2fd719bcb0e83cb39cfee22ee800f98a56eceb3
("net/phy: micrel: Add workaround for bad autoneg").
Use genphy_read_status instead of dedicated ksz9031_read_status.
Fixes: bff5b4b37372 ("net: phy: micrel: add Microchip KSZ9131 initial driver")

Very rarely, the KSZ9031 will appear to complete autonegotiation, but
will drop all traffic afterwards. When this happens, the idle error
count will read 0xFF after autonegotiation completes. Reset the PHY
when in that state.
