mdio-sun4i: Fix a memory leak
If the probing of the regulator is deferred, the memory allocated by
'mdiobus_alloc_size()' will be leaking.
It should be freed before the next call to 'sun4i_mdio_probe()' which will
reallocate it.
Fixes: 4bdcb1dd9feb ("net: Add MDIO bus driver for the Allwinner EMAC")
