PCI: switchtec: Fix an error handling path in switchtec_pci_probe()
[ Upstream commit dec529b0b0572b32f9eb91c882dd1f08ca657efb ]
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.
Fixes: df25461119d9 ("PCI: switchtec: Fix stdev_release() crash after surprise hot remove")
