ipack: tpci200: fix many double free issues in tpci200_pci_probe

[ Upstream commit 57a16810 ]

The function tpci200_register called by tpci200_install and
tpci200_unregister called by tpci200_uninstall are in pair. However,
tpci200_unregister has some cleanup operations not in the
tpci200_register. So the error handling code of tpci200_pci_probe has
many different double free issues.

Fix this problem by moving those cleanup operations out of
tpci200_unregister, into tpci200_pci_remove and reverting
the previous commit 9272e5d0 ("ipack/carriers/tpci200:
Fix a double free in tpci200_pci_probe").

Fixes: 9272e5d0
