middle-end/97579 - fix VEC_COND_EXPR ISEL optab query

This fixes a mistake in the optab query done by ISEL.  It
doesn't fix the PR but shifts the ICE elsewhere.

2020-11-03  Richard Biener  <rguenther@suse.de>

	PR middle-end/97579
	* gimple-isel.cc (gimple_expand_vec_cond_expr): Use
	the correct types for the vcond_mask/vec_cmp optab queries.
