devlink: Fix reporter's recovery condition

[ Upstream commit bea0c5c942 ]

Devlink health core conditions the reporter's recovery with the
expiration of the grace period. This is not relevant for the first
recovery. Explicitly demand that the grace period will only apply to
recoveries other than the first.
