s390x: Fix Iex_Load instruction selectors for F128/D128 types

The s390x instruction selectors for Iex_Load of Ity_F128 and Ity_D128
types had a common typo that would lead to crashes when used.  So far this
bug didn't surface because Iex_Load is not emitted on s390x with these
types.

This fixes the typo.
