[PATCH] Fix 3 warnings in nvptx.c

[Jakub Jelinek]

Hi!

While testing the second PR90811 patch with nvptx offloading, I've noticed 3
warnings in nvptx.c.
The first two hunks are obvious, the last warning is about unused mode_label
variable.
Either we can do what the patch does, or another option is throw away
both the mode_jump and mode_label temporaries, keep the last hunk unmodified
and
-	*mode_jump = label_insn;
+	if (mode == GOMP_DIM_VECTOR)
+	  vector_jump = neuter_start;
+	else
+	  worker_jump = neuter_start;

	* config/nvptx/nvptx.c (nvptx_sese_number, nvptx_sese_pseudo): Don't
	wrap ei variable name in the declaration in ()s.
	(nvptx_single): Actually use mode_label variable.  Formatting fix.
