net: phy: realtek: Replace phy functions with non-locked version in rtl8211e_config_init() 

After calling phy_select_page() and until calling phy_restore_page(),
the mutex 'mdio_lock' is already locked, so the driver should use
non-locked version of phy functions. Or there will be a deadlock with
'mdio_lock'.

This replaces phy functions called from rtl8211e_config_init() to avoid
the deadlock issue.
