[ Upstream commit c6180a6237174f481dc856ed6e890d8196b6f0fb ]
If the server reboots multiple times, the client should rely on the server to tell it that it cannot reclaim state as per section 9.6.3.4 in RFC7530 and section 8.4.2.1 in RFC5661. Currently, the client is being to conservative, and is assuming that if the server reboots while state recovery is in progress, then it must ignore state that was not recovered before the reboot.
