authkey: Remove pa_authkey_load(), it's redundant

The only place where pa_authkey_load() was called was in
pa_authkey_load_auto(), and the only functionality that
pa_authkey_load() was to log a warning if load() fails. That log
message is now in pa_authkey_load_auto(), so pa_authkey_load() has no
use any more.
