usb: stop request thread before destroying request handler
Stop request thread first to make sure there is no pending tasks
when we destroy the request handler. Otherwise a request task
may run with request_handler_ being nullptr.
Also fix a line of log message.
BUG=None
TEST=No assertion fired on device close.
