Subject: [PATCH v2 net 4/4] net/fsl: xgmac_mdio: Fix incorrect iounmap when removing module

As reported by sparse: In the remove path, the driver would attempt to
unmap its own priv pointer - instead of the io memory that it mapped
in probe.

Fixes: 9f35a7342cff ("net/fsl: introduce Freescale 10G MDIO driver")
