[PATCH] btrfs: send: update command for protocol version check

[David Sterba <dsterba@suse.com>]

For a protocol and command compatibility we have a helper that hasn't
been updated for v3 yet. We use it for verity so update where necessary.

Fixes: 38622010a6de ("btrfs: send: add support for fs-verity")
