Use inventory_hostname instead of ansible_hostname

Changes

Use inventory_hostname instead of ansible_hostname.

It appears to me that the intention is to check if current host is the first one in the group, then I think it's best to use inventory_hostname as it will always work and also doesn't depend on gather_facts.

ansible_hostname will not work when the host as specified in inventory does not match the hostname discovered on server because of

• FQDN vs. not fully qualified;
• alias in ~/.ssh/config;
• DNS CNAME;
• or simply it's different on DNS from on server.
