[PATCH net-next] net: phy: marvell: unlock after phy_select_page() failure

[Dan Carpenter]

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")
