s390/pci: Report SCLP status on error events when no pdev is associated

Browse Source 
With commit 4ec6054e73 ("s390/pci: Report PCI error recovery results
via SCLP") SCLP reports are generated when recovery is performed in
response to an error event. If such an error event arrives but no pdev
is currently associated with the zdev, e.g. because it was removed or
not yet probed, no report is generated. Fix this by generating a report
specific to an error event for a zdev without an associated pdev.
