[SSSD] [PATCH] SSH: Ignore the default_domain_suffix

[Jakub Hrozek]

Honza, can you review, please?

To reproduce, just set default_domain_suffix on an IPA trust client to
the AD domain value in the [sssd] section:

[sssd]
services = nss, pac, sudo, pam, ssh
domains = linux.test
config_file_version = 2
default_domain_suffix = ad.example.com

Then request a host:
sss_ssh_knownhostsproxy ipa1.linux.test

btw default_domain_suffix is already ignored for the autofs responder.
