netfs: Update tracepoints in a number of ways

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.
