Typos in logical decoding

While reading the logical decoding code I noticed a few supposedly mistyped
comments, see the diff below.

Besides that, output_plugin_options argument of CreateInitDecodingContext
function is unused, and the function passes NIL to the corresponding argument
of StartupDecodingContext. This looks to me like a thinko.
