cifs: Add a tracepoint to track credits involved in R/W requests
Add a tracepoint to track the credit changes and server in_flight value
involved in the lifetime of a R/W request, logging it against the
request/subreq debugging ID. This requires the debugging IDs to be
recorded in the cifs_credits struct.
The tracepoint can be enabled with:
echo 1 >/sys/kernel/debug/tracing/events/cifs/smb3_rw_credits/enable
Also add a three-state flag to struct cifs_credits to note if we're
interested in determining when the in_flight contribution ends and, if so,
to track whether we've decremented the contribution yet.
