[PATCH] RPC: add a release_rqst callout to the RPC transport switch
The final place where congestion control state is adjusted is in
xprt_release, where each request is finally released. Add a callout
there to allow transports to perform additional processing when a
request is about to be released.
Test-plan:
Use WAN simulation to cause sporadic bursty packet loss. Look for significant
regression in performance or client stability.
