PCI/AER: Fix missing uevent on recovery when a reset is requested

Since commit 7b42d97e99d3 ("PCI/ERR: Always report current recovery
status for udev") AER uses the result of error_detected() as parameter
to pci_uevent_ers(). As pci_uevent_ers() however does not handle
PCI_ERS_RESULT_NEED_RESET this results in a missing uevent for the
beginning of recovery if drivers request a reset. Fix this by treating
PCI_ERS_RESULT_NEED_RESET as beginning recovery.
