[ Upstream commit 416ef713631937cf5452476a7f1041a3ae7b06c6 ]
Update devlink health fw fatal reporter state to "healthy" is needed by strictly calling devlink_health_reporter_state_update() after recovery was done by PCI error handler. This is needed when fw_fatal reporter was triggered due to PCI error. Poll health is called and set reporter state to error. Health recovery failed (since EEH didn't re-enable the PCI). PCI handlers keep on recover flow and succeed later without devlink acknowledgment. Fix this by adding devlink state update at the end of the PCI handler recovery process.
