net: mdio: thunder: Fix a double free issue in the .remove function

Browse Source 
[ Upstream commit a93a0a1587 ]

'bus->mii_bus' have been allocated with 'devm_mdiobus_alloc_size()' in the
probe function. So it must not be freed explicitly or there will be a
double free.

Remove the incorrect 'mdiobus_free' in the remove function.

Fixes: 379d7ac7ca ("phy: mdio-thunder: Add driver for Cavium Thunder SoC MDIO buses.")
