drivers:misc: ti-st: reinit completion before send
download firmware behaves differently at different times, when logs are enabled and the system is loaded, the wait_for_completion is able to wait for every send, However during other times the wait does not happen. So, for reliability reinitializing the completion before every send, makes sure the wait happens for every send.
