libgomp: Appease some static analyzers [PR106906]

While icv_addr[1] = false; assignments where icv_addr has void *
element type is correct and matches how it is used (in those cases
the void * pointer is then cast to bool and used that way), there is no
reason not to add explicit (void *) casts there which are there already
for (void *) true.  And, there is in fact even no point in actually
doing those stores at all because we set that pointer to NULL a few
lines earlier.  So, this patch adds the explicit casts and then
comments those out to show intent.

	* env.c (get_icv_member_addr): Cast false to void * before assigning
	it to icv_addr[1], and comment the whole assignment out.
