Fix bb-slp-pr97709.c after computed goto change

Looks like I tested the change for bb-slp-pr97709.c on an
older tree which did not have the error message so I had
missed one more place where the change was needed.

Anyways committed after testing to make sure the testcase passes
now.

gcc/testsuite/ChangeLog:

	* gcc.dg/vect/bb-slp-pr97709.c: Fix for computed goto
	pointers.
