base: remove integer return codes from PD-session

Browse Source 
The return code of assign_parent remained unused. So this patch
removes it.

The bind_thread function fails only due to platform-specific limitations
such as the exhaustion of ID name spaces, which cannot be sensibly
handled by the PD-session client. If occurred, such conditions used to
be reflected by integer return codes that were used for diagnostic
messages only. The patch removes the return codes and leaves the
diagnostic output to core.

Fixes #1842
