[PATCH net-next] net: phy: icplus: Call phy_restore_page() when phy_select_page() fails

[Dan Carpenter <dan.carpenter@oracle.com>]

Smatch warns that there is a locking issue in this function:

drivers/net/phy/icplus.c:273 ip101a_g_config_intr_pin()
warn: inconsistent returns '&phydev->mdio.bus->mdio_lock'.
  Locked on  : 242
  Unlocked on: 273

It turns out that the comments in phy_select_page() say we have to call
phy_restore_page() even if the call to phy_select_page() fails.
