bootstrap/97666 - really fix sizeof (bool) issue

Pastoed the previous fix too quickly, the following fixes the
correct spot - the memset, not the allocation.

2020-11-04  Richard Biener  <rguenther@suse.de>

	PR bootstrap/97666
	* tree-vect-slp.c (vect_build_slp_tree_2): Revert previous
	fix and instead adjust the memset.
