[S390] Improve address space check.
A data access in access-register mode always is a user mode access, the code to inspect the access-registers can be removed. The second change is to use a different test to check for no-execute fault. The third change is to pass the translation exception identification as parameter, in theory the trans_exc_code in the lowcore could have been overwritten by the time the call to check_space from do_no_context is done.
