[LU-11272] LNet Health: handle routing special case

• Type: Bug
• Resolution: Fixed
• Priority: Blocker
• Fix Version/s: Lustre 2.12.0
• Affects Version/s: Lustre 2.12.0
• Severity: 3
• Assignee: Amir Shehata (Inactive)
• Reporter: Amir Shehata (Inactive)

Description

There are two issues:

1. A router checker ping can timeout, causing the mdh to be invalidated. We need to recreate the mdh in that case
2. When re-transmitting a message, even if the peer is marked as down we should re-transmit the message to fulfill it's retry quota.
