PCI: switchtec: Fix an error handling path in switchtec_pci_probe() 

[ Upstream commit dec529b0b0 ]

The commit in Fixes changed the logic on how resources are released and
introduced a new switchtec_exit_pci() that need to be called explicitly in
order to undo a corresponding switchtec_init_pci().

This was done in the remove function, but not in the probe.

Fix the probe now.
