Commit 3688fec8923 ("memory: Add Error** argument to .log_global_start()
handler") enabled vhost_log_global_start() to return a proper error, but
did not change it to do so; instead, it still aborts the whole process
on error.This crash can be reproduced by e.g. killing a virtiofsd daemon before initiating migration. In such a case, qemu should not crash, but just make the attempted migration fail.
