net: phy: marvell: unlock after phy_select_page() failure
We need to call phy_restore_page() even if phy_select_page() fails.
Otherwise we are holding the phy_lock_mdio_bus() lock. This requirement
is documented at the start of the phy_select_page() function.
Fixes: a618e86da91d ("net : phy: marvell: Speedup TDR data retrieval by only changing page once")
