ipack/carriers/tpci200: Fix a double free in tpci200_pci_probe
In the out_err_bus_register error branch of tpci200_pci_probe,
tpci200->info->cfg_regs is freed by tpci200_uninstall()->
tpci200_unregister()->pci_iounmap(..,tpci200->info->cfg_regs)
in the first time.
But later, iounmap() is called to free tpci200->info->cfg_regs
again.
My patch sets tpci200->info->cfg_regs to NULL after tpci200_uninstall()
to avoid the double free.
