fuse: add fuse_request_sent tracepoint
This new tracepoint complements fuse_request_send (enqueue) and
fuse_request_end (completion). It fires after the request has been
successfully copied to the daemon's buffer, just before the daemon
can start to process it.
fuse_request_sent does not fire if the copy of the request fails.
It also does not fire for NOTIFY_REPLY, which fires the _end tracepoint
at the end of copy.
This is needed for tools tracking the in-flight state of user initiated
fuse requests.
