btrfs: use kvzalloc() to allocate clone_roots in btrfs_ioctl_send()
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.

Fixes: 818e010bf9d0 ("btrfs: replace opencoded kvzalloc with the helper")
