tests/prctl-sve: fix prctl(PR_SVE_GET_VL) return expected value printingesyr/tests-prctl-sve-fix
* tests/prctl-sve.c: Print the expected return value string based
on the value returned, similarly to the way it is done
in tests/prctl-sme.c:print_sme_vl_arg().
Fixes: v5.13~8 "tests: improve test coverage of prctl syscall decoder"
Closes: https://github.com/strace/strace/issues/251
