target/s390x: Fix MVCRL with a large value in R0
Using a large R0 causes an assertion error:
qemu-s390x: target/s390x/tcg/mem_helper.c:183: access_prepare_nf: Assertion `size > 0 && size <= 4096' failed.
Even though PoP explicitly advises against using more than 8 bits for the
size, an emulator crash is never a good thing.
Fix by truncating the size to 8 bits.
