Fixes issue where if the challenge-response cannot be updated, the incorrect error message is displayed

Browse Source 
If the PAM module cannot update the challenge response file (due to permissions errors, usually), the incorrect error message is displayed "Error communicating with YubiKey...".

This patch makes it so the correct error message is sent to the PAM client, which makes resolving this issue a lot easier.
