Refactor is_host_dc call based on file generation flags

[mpgn]

Conditionally call is_host_dc based on arguments for generating files.

Description

This pull request introduces a small but important change to the logic for determining whether to call the is_host_dc() method in the enum_host_info function in nxc/protocols/smb.py. The update ensures that is_host_dc() is only called under specific conditions related to the generation of hosts or krb5 files.

Key logic update:

• The call to is_host_dc() is now conditioned to only run if either generate_hosts_file or generate_krb5_file arguments are set, or if neither is set, ensuring more precise control over when domain controller detection occurs. [1] [2]
