net: hisilicon: Fix usage of uninitialized variable in function mdio_sc_cfg_reg_write()
[ Upstream commit 53de429f4e88f538f7a8ec2b18be8c0cd9b2c8e1 ]
In function mdio_sc_cfg_reg_write(), variable "reg_value" could be
uninitialized if regmap_read() fails. However, "reg_value" is used
to decide the control flow later in the if statement, which is
potentially unsafe.
