powerpc/eeh: Use result of error_detected() in uevent

[ Upstream commit 704e5dd1c02371dfc7d22e1520102b197a3b628b ]

Ever since uevent support was added for AER and EEH with commit
856e1eb9bdd4 ("PCI/AER: Add uevents in AER and EEH error/resume"), it
reported PCI_ERS_RESULT_NONE as uevent when recovery begins.

Commit 7b42d97e99d3 ("PCI/ERR: Always report current recovery status for
udev") subsequently amended AER to report the actual return value of
error_detected().

Make the same change to EEH to align it with AER and s390.
