IBM Z: Fix address of operands will never be NULL warnings

Browse source 
Since a recent enhancement of -Waddress a couple of warnings are emitted
and turned into errors during bootstrap:

gcc/config/s390/s390.md:12087:25: error: the address of 'operands' will never be NULL [-Werror=address]
12087 |   "TARGET_HTM && operands != NULL
build/gencondmd.c:59:12: note: 'operands' declared here
   59 | extern rtx operands[];
      |            ^~~~~~~~

Fixed by removing those non-null checks.

gcc/ChangeLog:

	* config/s390/s390.md ("*cc_to_int", "tabort", "*tabort_1",
	"*tabort_1_plus"): Remove operands non-null check.
