Fix a boundary condition where in some cases an eeh event with
state == pci_channel_io_perm_failure wont be passed on to a driver
attached to the virtual pci device associated with a slice. This will
happen in case the slice just before (n-1) doesn't have any vPHB bus
associated with it, that results in an early return from
cxl_pci_error_detected callback.
With state==pci_channel_io_perm_failure, the adapter will be removed
irrespective of the return value of cxl_vphb_error_detected. So we now
always return PCI_ERS_RESULT_DISCONNECTED for this case i.e even if
the AFU isn't using a vPHB (currently returns PCI_ERS_RESULT_NONE).
Fixes: e4f5fc001a6("cxl: Do not create vPHB if there are no AFU configuration
records")
