Add note about unused arguments for pg_replication_origin_xact_reset() in docs. 

In 9.5, two arguments were introduced into pg_replication_origin_xact_reset()
by mistake while they are actually not used at all. We cannot fix this issue
for 9.5 anymore because it needs a catalog version bump. Instead, we add
a note about those unused arguments into the document.

Cancel the effects of
<function>pg_replication_origin_xact_setup()</function>.
Note that two arguments were introduced <emphasis>by mistake</>
during the <productname>PostgreSQL</> 9.5 development cycle while
<function>pg_replication_origin_xact_reset()</function> actually
doesn't use them at all. Therefore, any dummy values except
<literal>NULL</> can be safely specified as the arguments.
This mistake will be fixed in a future release.
