[PATCH] arm64/ptrace: Fix an error handling path in sve_set_common()

From: Christophe JAILLET
Date: Mon Jul 17 2023 - 13:55:18 EST


All error handling paths go to 'out', except this one. Be consistent and
also branch to 'out' here.

This patch is based on analysis of the surrounding code and should be
reviewed with care !

If the patch is wrong, maybe a comment in the code could explain why.
