ipa_sam was modifying the buffer returned by ipa_gethostfqdn(). Subsequent calls to ipa_gethostfqdn() returned the corrupt data, causing other operations to fail. Update ipa_sam to copy the string and modify the copy. Also document this characteristic of ipa_gethostfqdn() and explain that callers must not modify the returned data.
