Some error handling segments of rsxx_pci_probe() do not return error code,
so add error code for these segments.

Maybe there are some valid parts to the patch, but the two above at

ida_alloc or pci_enable_device, why are you overriding them?
Ah, sorry for these incorrect parts...
I will send a new patch.
