Make a number of updates to the netfs tracepoints:
(1) Remove a duplicate trace from netfs_unbuffered_write_iter_locked().
(2) Move the trace in netfs_wake_rreq_flag() to after the flag is cleared
so that the change appears in the trace.
(3) Differentiate the use of netfs_rreq_trace_wait/woke_queue symbols.
(4) Don't do so many trace emissions in the wait functions as some of them
are redundant.
(5) In netfs_collect_read_results(), differentiate a subreq that's being
abandoned vs one that has been consumed in a regular way.
(6) Add a tracepoint to indicate the call to ->ki_complete().
(7) Don't double-increment the subreq_counter when retrying a write.
(8) Move the netfs_sreq_trace_io_progress tracepoint within cifs code to
just MID_RESPONSE_RECEIVED and add different tracepoints for other MID
states and note check failure.
