[LU-15102] Reset lnet_ni::ni_ping_count when rx is finalized, not tx

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.15.0
• Severity: 3

Description

The lnet_ni:ni_ping_count is currently reset on every (healthy) tx. We should only reset it when receiving a message over the NI. Taking net_lock 0 on every tx results in a performance loss for certain workloads.
