s390x/tcg: Fix m5 vs. m4 field for VECTOR MULTIPLY SUM LOGICAL
The element size is located in m5, not in m4. As there is no m4, qemu
currently crashes with an assertion, trying to lookup that field.
Reproduced and tested via GO, which ends up using VMSL once the
Vector enhancements facility is around for verifying certificates with
elliptic curves.
