Check mode missing in one task

[Jan Stenvall]

Hello,

In the task Create temporary file for raw gossip encryption key in the file nix.yml check mode is missing. This task sets the variable consul_raw_key_file, and it must do so also in check mode, otherwise the following task fails: Write gossip encryption key locally for use with new servers

This is simple to fix by adding check_mode: false on line 111 in nix.yml.

Thanks a lot for your effort and support!

Sure, no problem. See #580.
