From: Denis Efremov <efre...@linux.com> commit 8eb2fd00153a3a96a19c62ac9c6d48c2efebe5e8 upstream.
btrfs_ioctl_send() used open-coded kvzalloc implementation earlier. The code was accidentally replaced with kzalloc() call [1]. Restore the original code by using kvzalloc() to allocate sctx->clone_roots.
