exec: Remove dead code (CID 1432876)
We removed the global_locking field in commit 4174495408a, leaving dead code around the 'unlocked' variable. Remove it to fix the DEADCODE issue reported by Coverity (CID 1432876). Fixes: 4174495408a ("exec: Remove MemoryRegion::global_locking field") Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20201030153752.1557776-1-philmd@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
