net: mdio: thunder: Fix a double free issue in the .remove function
[ Upstream commit a93a0a15876d2a077a3bc260b387d2457a051f24 ]
'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: 379d7ac7ca31 ("phy: mdio-thunder: Add driver for Cavium Thunder SoC MDIO buses.")
