rproc_del() waits on firmware_loading_complete in order to
make sure rproc_add() completed successfully before calling
rproc_shutdown(). However since rproc_add() will always be
called before rproc_del(), we do not need to wait on
firmware_loading_complete. Drop this completion variable
altogether.
