net/fsl: xgmac_mdio: Fix incorrect iounmap when removing module
commit 3f7c239c7844d2044ed399399d97a5f1c6008e1b upstream.
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")
