net: hns: Fix wrong read accesses via Clause 45 MDIO protocol

[ Upstream commit cec8abba13e6a26729dfed41019720068eeeff2b ]

When reading phy registers via Clause 45 MDIO protocol, after write
address operation, the driver use another write address operation, so
can not read the right value of any phy registers. This patch fixes it.
